“Mortgage, To” From Concise Bible Dictionary:
On the return of the Jews from exile, there were many poor, and in order to get food they borrowed money on their land, which gave the lender a claim on the property, even as mortgages are now negotiated. The money was lent by rich Jews, and Nehemiah was very angry at their exacting usury and strongly condemned them. They ought to have given sustenance to their poorer brethren (Neh. 5:3).
“Pledge” From Concise Bible Dictionary:
The taking of articles as security for loans, etc. was very early practiced, and restrictions were given in the law that no unfair advantage should be taken thereby (Ex. 22:26; Deut. 24:10-17; Job 22:6; Job 24:3,9; Amos 2:8). In 2 Kings 18:23 and Isaiah 36:8 the sense is “to make an engagement or treaty.”
