Samson's father Manoah did not recognize the Angel of the Lord until after he and the angel sacrificed to the Lord (Judges 13:16)
The angel of the LORD replied, βEven though you detain me, I will not eat any of your food. But if you prepare a burnt offering, offer it to the LORD.β (Manoah did not realize that it was the angel of the LORD.)
