No one presumed to speak for God. Credit for the text was printed clearly. It couldn’t have been more obvious.
This is Jeremiah 17:13:
O LORD, the hope of Israel, all that forsake thee shall be ashamed, and they that depart from me shall be written in the earth, because they have forsaken the LORD, the fountain of living waters.
The poster made up the rap verses. It has nothing to do with Jeremiah. The poster is a fraud. Might as well have been Samuel Jackson making up a fictitious version of Ezekiel 25:17.
