The eighth commandment forbids stealing - this includes anything which unjustly benefits our wealth or unjustly hinders someone else's wealth. We should be givers, not grabbers.

Exodus 20:15

15 “You shall not steal.

(ESV)

Ephesians 4:28

28 Let the thief no longer steal, but rather let him labor, doing honest work with his own hands, so that he may have something to share with anyone in need.

(ESV)
