Hebrews 11:8-10; Hebrews 11:17-19

8 By faith Abraham, when he was called to go out into a place which he should after receive for an inheritance, obeyed; and he went out, not knowing whither he went.

9 By faith he sojourned in the land of promise, as in a strange country, dwelling in tabernacles with Isaac and Jacob, the heirs with him of the same promise:

10 For he looked for a city which hath foundations, whose builder and maker is God.

17 By faith Abraham, when he was tried, offered up Isaac: and he that had received the promises offered up his only begotten son,

18 Of whom it was said, That in Isaac shall thy seed be called:

19 Accounting that God was able to raise him up, even from the dead; from whence also he received him in a figure.
