Hebrews 6:13 In-Context

11 And we desire every one of you to show the same diligence to the full assurance of hope to the end:
12 That ye be not slothful, but followers of them who through faith and patience inherit the promises.
13 For when God made promise to Abraham, because he could swear by no greater, he swore by himself,
14 Saying, Surely blessing I will bless thee, and multiplying I will multiply thee.
15 And so, after he had patiently endured, he obtained the promise.
