The Israel Ministry Of Health published this guidance on returning to Israel:
Who is permitted to enter Israel?
Entry into Israel is permitted to any citizen or resident of Israel, but they are obliged to be isolated upon their arrival from abroad.
All foreign nationals are denied entry to Israel.
In exceptional cases, one may apply for approval of the Foreign Ministry subject to proof of the ability to remain in home isolation for 14 days upon arrival in Israel.
Therefore it could be very hard/impossible to return.
Regarding whether the border is open, it is. The Israel Airports Authority published updated info on opening times and the border crossing is listed as the Menachim Begin Terminal there. The rules/guidance for the border can be viewed here.
