'Loyalty' in the Bible

He gives great victories to His king;He shows loyalty to His anointed,to David and his descendants forever.

For I am ever aware of your faithfulness, and your loyalty continually motivates me.

"What profit is there in taking my life, in my descending into the Pit? Can the dust of the grave praise you? Can it declare your loyalty?

He [my companion] has put out his hands against those who were at peace with him;He has broken his covenant [of friendship and loyalty].

A psalm of David. I will sing about loyalty and justice! To you, O Lord, I will sing praises!
