John Gill Commentary 2 Samuel 14:33

"So Joab came to the king, and told him; and when he had called for Absalom, he came to the king, and bowed himself on his face to the ground before the king: and the king kissed Absalom." — 2 Samuel 14:33 (ASV)

So Joab came to the king, and told him
What Absalom had said to him:

and when he had called for Absalom ;
sent messengers to his house to order him to come to him:

he came to the king, and bowed himself on his face to the ground before
the king ;
made a very reverend bow to him, according to the custom of those times, throwing himself at his feet in great submission to him:

and the king kissed Absalom ;
in token of his reconciliation to him; which laid the foundation of his after troubles from him, related in the following chapters.
