An Oath in which it was impossible for God to lie KJV

Genesis 22:15-19 And the angel of the LORD called unto A'-bra-ham out of heaven the second time,

And said, By myself have I sworn, saith the LORD, for because thou hast done this thing, and hast not withheld thy son, thine only son;

That in blessing I will bless thee, and in multiplying I will multiply thy seed as the stars of the heaven, and as the sand which is upon the sea shore; and thy seed shall possess the gate of his enemies'

And in thy seed shall all the nations of the earth be blessed; because thou hast obeyed my voice.

So A'-bra-ham returned unto his young men, and they rose up and went together to Beer-she'-ba; and A'-bra-ham dwelt with Beer-she'-ba.

Hebrews 3:4-6 For every house is builded by some man; but he that built all things is God.

And Mo'-ses verily was faithful  in all his house, as a servant, for a testimony of those things which were to be spoken after;

But Christ as a son over his own house; whose house are we, if we hold fast the confidence and the rejoicing of the hope firm unto the end.

Hebrews 9:1-8 Then verily the first covenant had also ordinances of divine service, and a worldly sanctuary.

For there was a tabernacle made; the first, wherein was a candlestick, and the table, and the shewbread; which is called the sanctuary.

And after the second veil, the tabernacle which is called the Holiest of all;

Which had the golden censer, and the ark of the covenant overlaid round about with gold, wherein was the golden pot that had man'-na, and Aa'-ron's rod that budded, and the tables of the covenant;

And over it the cher'-u-bims of glory shadowing the mercyseat; of which we cannot now speak particularly.

Now when these things were thus ordained, the priests went always into the first tabernacle, accomplishing the service of God.

But into the second went the high priest alone once every year, not without blood, which he offered for himself, and for the errors of the people;

The Holy Ghost this signifying, that the way into the holiest of all was not yet made manifest, while as the first tabernacle was yet standing:

Hebrews 5:5-11 So also Christ glorified not himself to be made an high priest; but he that said unto him, Thou art my Son, to day have I begotten thee.

As he saith also in another place, Thou art a priest for ever after the order of Mel-chis'-e-dec.

Who in the days of his flesh, when he had offered up prayers and supplications with strong crying and tears unto him that was able to save him from death, and was heard in that he feared;

Though he were a Son, yet learned he obedience by the things which he suffered;

And being made perfect, he became the author of eternal salvation unto all them that obey him;

Called of God an high priest after the order of Mel-chis'-e-dec.

Of whom we have many things to say, and hard to be uttered, seeing ye are dull of hearing.
