“COVENANT” [διαθηκη]— “a disposition, arrangement, of any sort, which one wishes to be valid, the last disposition which one makes of his earthly possessions after his death, a testament or will / a compact, a covenant, a testament” (used 33 times in the Greek; The KJV translates 14 of these as “testament,” but almost all the new translations use “covenant” instead, more accurate to our modern vernacular, and more consistent in translations (since the SAME Greek word should be translated the SAME way as long as context doesn’t suggest Old Testament otherwise; and because the word testament narrows the meaning too much
[Merriam-Webster=”the legal instructions in which you say who should receive your property, possessions, etc., after you die”]; by contrast, covenant is more generic, and can also mean a testament.).
Matthew 26:28—for this is My blood of the covenant, which is poured out for many for the forgiveness of sins.

1 Corinthians 11:25—In the same way also he took the cup, after supper, saying, “This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me.”
[NOTE: The life is in the blood, and it is as though Christ’s Blood is what gave life to the New Covenant, and brings life to those who keep this covenant of grace.]

Galatians 3:15—Brethren, I speak in the manner of men: Though it is only a man’s covenant, yet if it is confirmed, no one annuls or adds to it.
ESV: To give a human example, brothers: even with a man-made covenant, no one annuls it or adds to it once it has been ratified.
Galatians 3:17—And this I say, that the law, which was 430 years later, cannot annul the Covenant that was confirmed before by God in Christ, that it should make the promise of no effect.
ESV: This is what I mean: the law, which came 430 years afterward, does not annul a covenant previously ratified by God, so as to make the promise void.

9—”not according to the covenant that I made with their fathers in the day when I took them by the hand to lead them out of the land of Egypt; because they did not continue in My covenant, and I disregarded them, says the LORD.
10—”For this is the covenant that I will make with the house of Israel after those days, says the LORD: I will put My laws in their mind and write them on their hearts; and I will be their God, and they shall be My people.
13—In that He says, “A new Covenant,” He has made the first obsolete. Now what is becoming obsolete and growing old is ready to vanish away.

16—For where there is a testament, there must also of necessity be the death of the testator.
