1 Samuel 25:5–11, 21
So David sent ten young men and instructed them, “Go up to Nabal at Carmel. Greet him in my name / and say to him, ‘Long life to you, and peace to you and your house and to all that belongs to you. / Now I hear that it is time for shearing. When your shepherds were with us, we did not harass them, and nothing of theirs was missing the whole time they were in Carmel.
