Leviticus 19:12 In-Context

10 It is the same with your grape crop—do not strip every last bunch of grapes from the vines, and do not pick up the grapes that fall to the ground. Leave them for the poor and the foreigners living among you. I am the LORD your God.
11 “Do not steal. “Do not deceive or cheat one another.
12 “Do not bring shame on the name of your God by using it to swear falsely. I am the LORD .
13 “Do not defraud or rob your neighbor. “Do not make your hired workers wait until the next day to receive their pay.
14 “Do not insult the deaf or cause the blind to stumble. You must fear your God; I am the LORD .
