'Changed' in the Bible

{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.

They shall perish, but thou continuest; and all of them shall grow old as a garment: as a vesture shalt thou change them, and they shall be changed.

And they changed their glory into the similitude of an ox that eateth grass.
