Hebrews 6:13 In-Context

11 And we desire that every one of you shew forth the same carefulness to the accomplishing of hope unto the end:
12 That you become not slothful, but followers of them who through faith and patience shall inherit the promises.
13 For God making promises to Abraham, because he had no one greater by whom he might swear, swore by himself,
14 Saying: Unless blessing I shall bless thee and multiplying I shall multiply thee.
15 And so patiently enduring he obtained the promise.
