Hebrews 11:17-19

JPS_ASV_Byz(i) 17 By faith Abraham, being tried, offered up Isaac; yea, he that had gladly received the promises was offering up his only begotten son, 18 even he to whom it was said, In Isaac shall thy seed be called: 19 accounting that God is able to raise up, even from the dead, from whence he did also in a figure receive him back.
