'Faithfulness' in the Bible

I will even betroth thee unto me in faithfulness: and thou shalt know the LORD.

Listen to the word of the Lord, O sons of Israel,For the Lord has a case against the inhabitants of the land,Because there is no faithfulness or kindnessOr knowledge of God in the land.

What am I going to do with you, O Ephraim? What am I going to do with you, O Judah? For your faithfulness is as fleeting as the morning mist; it disappears as quickly as dawn's dew!

For I delight in faithfulness, not simply in sacrifice; I delight in acknowledging God, not simply in whole burnt offerings.
