The Hebrew rekush refers to movable property β goods, cattle, and wealth accumulated through labor or acquisition. It appears frequently in narratives of migration and conquest: Abraham left Egypt with great rekush (Genesis 12:5; 13:6), Lot and Abraham's combined rekush was so great the land couldn't support them both, and Israel left Egypt with Egypt's rekush (plunder).
The rekush of the patriarchs represents God's covenant blessing made tangible in history. God promised Abraham He would bless him and make him great (Genesis 12:2), and rekush was one visible sign of that blessing. Yet the same rekush that blessed could also separate β Lot's separation from Abraham was caused by their combined rekush (Genesis 13:6). Wealth is a test of character and stewardship; the question Scripture always asks is what we do with the rekush God has entrusted to us.
