'Kissed' in the Bible

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.

It was so, that when any man came near to do him obeisance, he put forth his hand, and took hold of him, and kissed him.

All the people went over the Jordan, and the king went over. Then the king kissed Barzillai, and blessed him; and he returned to his own place.
