'Behaviour' in the Bible

And he changed his behaviour before them, and feigned himself mad in their hands, and scratched on the doors of the gate, and let his spittle fall down on his beard.

{A Psalm of David; when he changed his behaviour before Abimelech, who drove him away, and he departed.} I will bless Jehovah at all times; his praise shall continually be in my mouth.
