Sir 5:15
King James Version
“Be not ignorant of any thing in a great matter or a small.”
Context
12If thou hast understanding, answer thy neighbour; if not, lay thy hand upon thy mouth.
13Honour and shame is in talk: and the tongue of man is his fall.
14Be not called a whisperer, and lie not in wait with thy tongue: for a foul shame is upon the thief, and an evil condemnation upon the double tongue.
15Be not ignorant of any thing in a great matter or a small.
