An Oath by Someone Who Can't Lie NKJV

Hebrews 10:36-39 For you have need of endurance, so that after you have done the will of God, you may receive the promise;

"For yet a little while, And he who is coming will come and will not tarry.

Now the just shall live by faith; But if anyone draws back, My soul has no pleasure in Him."

But we are not of those who draw back to perdition, but of those who believe to the saving of the soul.

Genesis 22:15-19 Then the Angel of the Lord called to Abraham a second time out of heaven,

and said, "By Myself I have sworn, says the Lord, because you have done this thing, and have not withheld your son, your only son--

"blessing I will bless you, and multiplying I will multiply your descendants as the stars of the heaven and as the sand which is on the seashore; and your descendants shall possess the gate of their enemies.

"in your seed all the nations of the earth shall be blessed, because you have obeyed My voice."

So Abraham returned to his young men, and they rose  and went together to Beersheba; And Abraham dwelt at Beersheba.

Hebrews 3:4-6 For every house is built by someone, but He who built all things is God.

And Moses indeed was faithful in all his house as a servant, for a testimony of those things which would be spoken afterward,

but Christ as a Son over His own house, whose house we are if we hold fast the confidence and the rejoicing of the hope firm to the end.

Hebrews 9: 1-8 Then indeed, even the first covenant had ordinances of divine service and the earthly sanctuary.

For a tabernacle was prepared; the first part, in which was the lampstand, the table, and the show-bread, which is called the sanctuary;

and behind the second veil, the part of the tabernacle which is called the Holiest of All,

which had the golden censer and the ark of the convenant overlaid on all sides with gold, in which were the golden pot that had the manna, Aaron's rod that budded, and the tablets of the convenant;

and above it were the cherubim of glory overshadowing the mercy seat, Of these things we can now speak in detail.

Now when these things had been thus prepared, the priests always went into the first part of the tabernacle, performing the services.

But into the second part the high priest went alone once a year, not without blood, which he offered for himself and for the people's sins committed in ignorance;

the Holy Spirit indication this, that the way into the Holiest of All was not made manifest while the first tabernacle was still standing.

Hebrews 5:5-11 So also Christ did not glory Himself to become High Priest, but it was He who said to Him; ‘You are My Son, Today I have begotten You.”

As He also says in another place; “You are a priest forever According to the order of Melchizedek,”

who, in the days of His flesh, when He had offered up prayers and supplications, with vehement cries and tears to Him who was able to save Him from death, and was heard because of His godly fear,

through He was a Son, yet He learned obedience by the things which He suffered,

And having been perfected, He became the author of eternal salvation to all who obey Him,

called by God as High Priest “according to the order of Melchizedek,”

of whom we have much to say, and hard to explain, since you have become dull of hearing.
