'Forming' in the Bible

Then it shall come about, when many evils and troubles have come on them, that this [sacred] song will confront them as a witness; for it will not be forgotten from the mouth of their descendants. For I know their inclination which is developing even now, before I bring them into the land which I have sworn to give them.”

“The east side, from between Hauran, Damascus, Gilead, and the land of Israel, shall be the Jordan; from the north border to the eastern sea you shall measure. This is the east side.
