'Redeeming' in the Bible

The Angel [that is, the Lord Himself] who has redeemed me [continually] from all evil,Bless the boys;And may my name live on in them [may they be worthy of having their names linked with mine],And the names of my fathers Abraham and Isaac;And may they grow into a [great] multitude in the midst of the earth.”

Now formerly in Israel this was the custom concerning redeeming and exchanging property. To confirm a transaction, a man pulled off his sandal and gave it to the other. This was the way of confirming and attesting in Israel.
