Deuteronomy 6:13

⁸Jesus answered him, “Get behind me, Satan! For it is written, ‘You shall worship the Lord your God, and you shall serve him only.’”

²⁰You shall fear the LORD your God. You shall serve him. You shall cling to him, and you shall swear by his name.

¹⁰Then Jesus said to him, “Get behind me,^[+] Satan! For it is written, ‘You shall worship the Lord your God, and you shall serve him only.’”

⁴You shall walk after the LORD your God, fear him, keep his commandments, and obey his voice. You shall serve him, and cling to him.

¹²“‘You shall not swear by my name falsely, and profane the name of your God. I am the LORD.

¹²Now, Israel, what does the LORD your God require of you, but to fear the LORD your God, to walk in all his ways, to love him, and to serve the LORD your God with all your heart and with all your soul,

¹¹But the king shall rejoice in God. Everyone who swears by him will praise him, for the mouth of those who speak lies shall be silenced.

²³I have sworn by myself. The word has gone out of my mouth in righteousness, and will not be revoked, that to me every knee shall bow, every tongue shall take an oath.

¹⁶It will happen, if they will diligently learn the ways of my people, to swear by my name, ‘As the LORD lives;’ even as they taught my people to swear by Baal, then they will be built up in the middle of my people.

¹⁶so that he who blesses himself in the earth will bless himself in the God of truth; and he who swears in the earth will swear by the God of truth; because the former troubles are forgotten, and because they are hidden from my eyes.
