Proverbs 22:7 is one of my favorite readings in the bible that deals with money. Every time I read this passage, I always want to get out of debt and pay back everything I owe.
To me Psalm 22:7 talks about how you are a slave to a person or thing you borrow from and that you will always have that on your shoulders until you fully pay it back.
Here are two different bible translations of Psalms 22:7
7 The rich rule over the poor,
and the borrower is slave to the lender.
New Revised Standard Version (NRSV)
The rich rule over the poor,
and the borrower is the slave of the lender.
