But, when found, he will make it good with seven times as much; all the valuables of his house he will give.

Whether he is despised or not, when caught, the thief is punished. Under the Mosaic law the thief was to pay double, fourfold or fivefold, according to the items stolen and the circumstances. (Ex. 22:1, 4, 7) Here in Proverbs 6 ‘sevenfold’ likely means a complete payment, according to what the judges would assess, “seven” often being used to denote completeness. Or it may mean that, in order to appease the injured party and establish peace with him, it could cost the thief all he owned.
