Now therefore beware, I pray thee, and drink no wine nor strong drink, and eat not any unclean thing:

And the man said unto Joab, Though I should receive a thousand pieces of'silver in my hand, yet would I not put forth my hand against the king's son; for in our hearing the king charged thee and Abishai and Ittai, saying, Beware that none touch the young man Absalom.

And the man of God sent unto the king of Israel, saying, Beware that thou pass not such a place; for thither the Syrians are coming down.

Beware lest ye say, We have found wisdom; God may vanquish him, not man:

Beware lest Hezekiah persuade you, saying, Jehovah will deliver us. Hath any of the gods of the nations delivered his land out of the hand of the king of Assyria?
