'Trustworthiness' in the Bible

Yahweh, you [are] my God; I will exalt you. I will praise your name, for you have done wonderful things, plans {of old}, [in] faithfulness, trustworthiness.

Whoever blesses himself in the land shall bless himself by the God of trustworthiness, and the one who swears an oath in the land shall swear by the God of trustworthiness, because the former troubles are forgotten, and they are hidden from my eyes.
