6 Bible Verses about God Swearing Blessings

For when God made a promise to Abraham, since He could not make a vow by anyone greater, He vowed by Himself, saying [Gen. 22:16-17], "I will certainly bless you and will multiply [your descendants]."

[This Agreement was] the oath by which He swore to Abraham, our forefather,

Since he was a prophet and knew that God had pledged His word that one of his [i.e., David's] descendants would sit on his throne [as king];

(for [Levitical] priests were appointed without [God] taking [such] an oath, but Christ was appointed with an oath by God when He said to Him [Psa. 110:4], "The Lord made a vow and will not change His mind [when He said], 'You are a priest forever')."

And this was not done without the taking of an oath [by God],

Since God wanted to show conclusively to those who would inherit the promise [i.e., Abraham and all of his spiritual descendants], how unchangeable His purpose was, He confirmed it with an oath.
