1 Chronicles 19:5

When someone came and told David about his men, he sent messengers to meet them, since the men had been thoroughly humiliated. The king told them, “Stay in Jericho until your beards have grown back, and then return.”

Then there went certain, and told David how the men were served. And he sent to meet them: for the men were greatly ashamed. And the king said, Tarry at Jericho until your beards be grown, and then return.
