'Advise' in the Bible

When Hushai approached Absalom, Absalom asked him, "Here's what Ahithophel had to advise. Should we do what he says? Or if not, say so!"

Instead, I advise that all Israel from Dan to Beer-sheba—as numerous as the sand by the sea—be gathered to you and that you personally go into battle.

So Gad came to David, and told him, and said unto him, Shall seven years of famine come unto thee in thy land? or wilt thou flee three months before thine enemies, while they pursue thee? or that there be three days' pestilence in thy land? now advise, and see what answer I shall return to him that sent me.
