'Feigned' in the Bible

{A Prayer of David.} Hear the right, O LORD, attend unto my cry, give ear unto my prayer, that goeth not out of feigned lips.

As soon as they hear me, they respond and obey me;Foreigners feign obedience to me.

A Psalm of David when he feigned madness before Abimelech, who drove him away and he departed.I will bless the Lord at all times;His praise shall continually be in my mouth.

Say to God, “How awesome are Your works!Because of the greatness of Your power Your enemies will give feigned obedience to You.
