Is this a correct border for what God promised Abraham in the 1st covenant?
According to Wikipedia:
"This map representing biblical King David's Kingdom at the time of his death is probably close to a halachaic Greater Israel."1
According to Genesis 15:18 the second image is correct.
Genesis 15:18 – On that day the LORD made a covenant with Abraham, saying, “To your descendants I have given this land— from the river of Egypt to the great River Euphrates."
Therefore, the promised land extends from the Nile all the way to Iraq.
