Isn't "Jehovah-Jireh" (and other such names) just the name of a place?

The two word phrases where the first word is God's special four letter name and the second is descriptive ("is there"/shammah, "heals"/raphah, "is my banner"/nissi etc.) are often collected together by preachers. They are aspects which biblical characters choose to describe God, which make them important. They aren't all literally names, but they function like names, sometimes in pointing to a defining characteristic of God.

I note that there's a confusion about Exodus 3:14 - "I am what I am" - in another answer here and I've heard it elsewhere. That verse (http://biblehub.com/text/exodus/3-14.htm) doesn't contain the four letter name of God. The word for "I Am" / "I will be" has the letters AHYH and Exodus 3:14 links God with the verb "to be", whose root is HYH. it is plausible that the four letter name of God is related to this root, but not obvious. I think people get confused with Exodus 6:2-3 where God makes a big deal of telling Moses his four letter name, but there's no meaning of the name given. Also note that the four letter name appears practically everywhere in the Hebrew bible.

OP: Yet many Christians talk about these names for places in the Bible and say they are the names to God. Why do they do that? Is it a proper thing to do?

Basically, what we are reading is the name of God and His nature. God is salvation. God is provider. God is creator. God is banner. God is healer. God is sanctifier.

Some may have discovered the nature of God in a place, but that misses the point of God revealing His nature at a particular place. The alter of provision with Abraham and Isaac no longer exists, but the nature of God as provider certainly continues, even as it was fulfilled in Christ Jesus. Besides, there are scriptural places where the nature of God is revealed, though not at a place.

Some may call the nature a title, and that is true enough, but misses the point of God revealing His nature to us.

Example List of God's Nature

YHWH Rohi, the LORD is my shephard (Psalm 23)

YHWH Jireh, the LORD will provide (Gen 22:14)

YHWH Rapha, the LORD who heals (Exo 15:26)

YHWH Shalom, the LORD is peace (Judges 6:24) Again, the altar is gone, but God is still our peace.

I could go on, but believe the point is made. To answer the OP, the nature of God is not discovered in a place, but in His activities or relationships with us.

The Hebrew word יְהֹוָה יִרְאֶה, yĕhōwâ yirʾe (Strong's H3070): Jehovah-Jireh, is a symbolical name for Mount Moriah.

And Abraham called the name of that place Jehovah-jireh: as it is said to this day, In the mount of the LORD it shall be seen (Genesis 22:14 KJV)

Names such as Jehovah-Jireh, Jehovah-Nissi and Jehovah-Shalom are much more than simply place names. They also describe aspects of God’s many-faceted character.

YHWH / YAHWEH / JEHOVAH: Translated in English Bibles “LORD” (all capitals) to distinguish it from Adonai, “Lord.” The revelation of the name is given to Moses “I Am who I Am” (Exodus 3:14). This name specifies an immediacy, a presence. Yahweh is present, accessible, near to those who call on Him for deliverance (Psalm 107:13), forgiveness (Psalm 25:11) and guidance (Psalm 31:3).

The following extracts from an article on this subject explain why the name has to do with the person and character of Yahweh/Jehovah:

YAHWEH-JIREH [yah-way-ji-reh]: “Jehovah-Jireh” is the KJV’s translation of YHWH-Yireh and means “The LORD Will Provide” (Genesis 22:14). It is the name memorialized by Abraham when God provided the ram to be sacrificed in place of Isaac.

Upon reaching the place God had chosen, Abraham demonstrates his faith and obedience by building an altar, binding Isaac, and placing him on the wood. Before Abraham can finish the offering, the Angel of the Lord calls to him from heaven, and Isaac’s life is spared. Then, “Abraham looked up and there in a thicket he saw a ram caught by its horns. He went over and took the ram and sacrificed it as a burnt offering instead of his son” (Genesis 22:13). Abraham names the place “Jehovah-Jireh” because of God’s gracious provision of a substitute for Isaac. Immediately afterwards, God reconfirms His covenant with Abraham (v 17-18). Centuries later, King Solomon would build the temple in the same location (2 Chronicles 3:1).

The account of Abraham on Mt. Moriah thus becomes more than a dramatic illustration of faith and obedience. It is a presentation of the Lord’s eternal grace, continual provision, and all-encompassing wisdom. Jehovah-Jireh is not “The LORD Did Provide,” but “The LORD Will Provide.” In other words, the name does not simply memorialize a past event; it anticipates a future action.

Likewise, the statement “on the mountain of the LORD it will be provided” (verse 14) refers to more than Mt. Moriah—it also refers to a hill called Calvary, where God “did not spare his own Son, but gave him up for us all” (Romans 8:32). Abraham’s faith-filled statement that “God himself will provide the lamb” is a companion to John the Baptist’s exclamation, “Look, the Lamb of God, who takes away the sin of the world!” (John 1:29).

You ask if it is proper to talk about these names for places in the Bible and say they are the names of God. Christians understand that adding ‘Jireh’ to the name of God describes His character and one of His many attributes.

Used reverentially, in acknowledgement of His sovereignty and grace, elicits our worship and praise as we trust in Him alone for all He has done, and all He is yet to do. It helps us to understand the significance of what happened on Mount Moriah when God provided the sacrifice that represents the ultimate sacrifice, that of His one, His only Son, who died so that we may live. The LORD will provide, and for this we are eternally indebted.

When you say "just the name of a place", I assume you mean "only the name of a place." If I have misunderstood, then read no further, for I am basing my answer on this assumption!

You ask about Hebrew language with this matter, and it is true that it can be difficult to get such names right. For instance, the Hebrew word beer means 'well' yet there is a mistranslation of this in the Numbers chapter 21 account of the wandering Israelites coming to what is said to be a place called Beer, to there find a well (verse 16). The correct translation should read, "From there they went to a [particular] well, that is the well whereof the Lord spake unto Moses, 'Gather the people together, and I will give them water.'" Unfortunately, even the A.V. says they went to Beer, putting a capital 'B' at the start of the word that should simply have remained as 'beer' - well.

Some Hebrew words never refer to a place, but only to (as in this instance) a well. Other Hebrew words never refer to an object but only to a name for either a person or a nation. This is shown in verse 13 where a name is applied to a location (Moab) and another name to a nation (Amorites).

The problem is not just limited to the Hebrew language, and perhaps an illustration from the English language will help with this question. There is a town in Britain called Kirkcaldy. There was also a family in that area with the surname, 'Kirkcaldy'. This name was given to a man who owned a large estate on the outskirts of the town. One of his descendants was called "William Kirkcaldy of Grange". His surname was Kirkcaldy, and his location of residence was the estate of Grange by that town. The surname and title ran through the family line for many generations. Then, when the last male descendant died without a male heir, the surname Kirkcaldy could only be used for female descendants, but if they married, their surname then became that of their husbands. The habit then arose of both male and female grandchildren of such ladies getting Kirkcaldy as a middle name. This went on down the line for several generations until the custom died out.

This meant, however, that there was a time when Kirkcaldy was both a surname and a place name - it was both. Much later on it became confusing for people of this generation who had never heard of it as a surname, or even a middle name, and only thought it was a place-name, for the place remains to this day.

This, I suggest, is the best way to view the matter in hand - that biblical names like Jehovah-Jireh etc combine the name of God with a place-name. Put both together and you can learn a deeper meaning of the One concerned, as the place-name speaks of particular qualities of God.
