Hebrews 6:11-15

11But we desire earnestly that each one of you shew the same diligence to the full assurance of hope unto the end;

12that ye be not sluggish, but imitators of those who through faith and patience have been inheritors of the promises.

13For 1God, having promised to Abraham, since he had no greater to swear by, swore by himself,

14saying, Surely blessing I will bless thee, and multiplying I will multiply thee;

15and thus, having had long patience, he got the promise.
