Pretenders; hypocrites.

Examine me, O LORD, and prove me; try my reins and my heart. For thy lovingkindness is before mine eyes: and I have walked in thy truth. I have not sat with vain persons, neither will I go in with DISSEMBLERS. I have hated the congregation of evildoers; and will not sit with the wicked. ( Psalm 26:2-5 )
