Put not forth thyself in the presence of the king, And stand not in the place of great men:
Be not forward (self-assertive and boastfully ambitious) in the presence of the king, and stand not in the place of great men;
Put not thyself forward in the presence of the king, And stand not in the place of great men:
Don’t exalt yourself in the presence of the king, or stand in the place of important people,
Do not appear glorious before the king, and do not stand in the place of the great.
