Proverbs 12:23 KJV — A prudent man concealeth knowledge: but the heart of fools proclaimeth foolishness.
Miriam said: shall I go and call to thee a nurse of the Hebrew women, that she may nurse the child for thee?
Miriam didn’t say: hey, that’s my brother. Shall I call our mum to look after him so you can pay us?
Prudence knows which knowledge to leave out when you’re having a conversation.
