'Faithfulness' in the Bible

but I show covenant faithfulness to the thousands who choose me and keep my commandments.

Rather it is because of his love for you and his faithfulness to the promise he solemnly vowed to your ancestors that the Lord brought you out with great power, redeeming you from the place of slavery, from the power of Pharaoh king of Egypt.

He is the Rock, his work is perfect, For all his ways are righteousness; A God of faithfulness without deceit, Just and right is he.

And he said, I will hide my face from them, I will see what their end shall be; For they are a perverse generation, Children in whom is no faithfulness.
