1. The confidence of an unfaithful man (so some read it) will be like a broken tooth; his policy, his power, his interest, all that which he trusted in to support him in his wickedness, will fail him in time of trouble, Psalm 52:7.
2. Confidence in an unfaithful man (so we read it), in a man whom we thought trusty and therefore depended on, but who proves otherwise; it proves not only unserviceable, but painful and vexatious, like a broken tooth, or a foot out of joint, which, when we put any stress upon it, not only fails us, but makes us feel from it, especially in time of trouble, when we most expect help from it; it is like a broken reed, Isaiah 36:6.
Confidence in a faithful God, in time of trouble, will not prove thus; on him we may rest and in him dwell at ease.
