'Faithfulness' in the Bible

Righteousness will be the sash around his loins, and faithfulness the belt around his waist."

then a throne will be established in gracious love, and there will sit in faithfulness in the Tent of David one who judges, seeks justice, and is swift to do what is right."

LORD, you are my God; I will exalt you and praise your name, for you have done marvelous things, plans made long ago in faithfulness and truth.

For Sheol cannot thank you, death cannot sing your praise; and those who go down to the Pit cannot hope for your faithfulness.

The living yes the living they thank you, just as I am doing today; fathers will tell their children about your faithfulness.

Then whoever takes an oath by the God of faithfulness, and whoever takes an oath in the land, will swear by the God of faithfulness, because the former troubles are forgotten and are hidden from my eyes.
