Hebrews 6:12-16

12We do not want you to become lazy, but to imitate those who through faith and patience inherit what has been promised.

13When God made his promise to Abraham, since there was no one greater for him to swear by, he swore by himself,

14saying, “I will surely bless you and give you many descendants.”

15And so after waiting patiently, Abraham received what was promised.

16People swear by someone greater than themselves, and the oath confirms what is said and puts an end to all argument.
