'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 do him obeisance, he put forth his hand, and took hold of him, and kissed him.

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