10 For God is not unrighteous to forget your work and labor of love, which you have showed toward his name, in that you have ministered to the saints, and do minister.
11 And we desire that every one of you do show the same diligence to the full assurance of hope unto the end:
12 That you be not slothful, but followers of them who through faith and patience inherit the promises.
13 For when God made a promise to Abraham, because he could swear by no greater, he swore by himself,
14 Saying,
15 And so, after he had patiently endured, he obtained the promise.
16 For men verily swear by the greater: and an oath for confirmation is to them an end of all strife.
