'Faithful' in the Bible

He guards the steps of His faithful ones,but the wicked perish in darkness,for a man does not prevail by his own strength.

“‘Then I will raise up a faithful priest for Myself. He will do whatever is in My heart and mind. I will establish a lasting dynasty for him, and he will walk before My anointed one for all time.

If I continue to live, treat me with the Lord’s faithful love, but if I die,

don’t ever withdraw your faithful love from my household—not even when the Lord cuts off every one of David’s enemies from the face of the earth.”

Ahimelech replied to the king: “Who among all your servants is as faithful as David? He is the king’s son-in-law, captain of your bodyguard, and honored in your house.
