References for 1 Chronicles 19:1
And David said, "I will deal kindly with Hanun the son of Nahash, for his father dealt kindly with me." So David sent messengers to console him concerning his father. And David's servants came to the land of the Ammonites to Hanun to console him.
But the princes of the Ammonites said to Hanun, "Do you think, because David has sent comforters to you, that he is honoring your father? Have not his servants come to you to search and to overthrow and to spy out the land?"
So Hanun took David's servants and shaved them and cut off their garments in the middle, at their hips, and sent them away;
and they departed. When David was told concerning the men, he sent messengers to meet them, for the men were greatly ashamed. And the king said, "Remain at Jericho until your beards have grown and then return."
When the Ammonites saw that they had become a stench to David, Hanun and the Ammonites sent 1,000 talents of silver to hire chariots and horsemen 2from Mesopotamia, from Aram-maacah, and from 3Zobah.
