Proverbs 20:21 in the King James Version
An inheritance may be gotten hastily at the beginning; but the end thereof shall not be blessed.
Context
20 Whoever curses his father or his mother, his lamp shall be put out in blackness of darkness.
21 An inheritance quickly gained at the beginning won’t be blessed in the end.
22 Don’t say, “I will pay back evil.” Wait for the LORD, and he will save you.
