'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.

And it was so, that when any man came nigh to him to do him obeisance, he put forth his hand, and took him, and kissed him.

And all the people went over Jordan. And when the king was come over, the king kissed Barzillai, and blessed him; and he returned unto his own place.
