My PhD research falls in the realm of creation and eschatology. In Jer 31:36 there is a little phrase: hahuqqim ha’elleh. The NASB (and ESV) translate this phrase as this fixed order. The context is the new covenant…
“Behold, days are coming,” declares the LORD, “when I will make a new covenant with the house of Israel and with the house of Judah, not like the covenant which I made with their fathers in the day I took them by the hand to bring them out of the land of Egypt, My covenant which they broke, although I was a husband to them,” declares the LORD. “But this is the covenant which I will make with the house of Israel after those days,” declares the LORD, “ I will put My law within them and on their heart I will write it; and I will be their God, and they shall be My people. “They will not teach again, each man his neighbor and each man his brother, saying, ‘Know the LORD,’ for they will all know Me, from the least of them to the greatest of them,” declares the LORD, “for I will forgive their iniquity, and their sin I will remember no more.”
Thus says the LORD, Who gives the sun for light by day, And the fixed order of the moon and the stars for light by night, Who stirs up the sea so that its waves roar; The LORD of hosts is His name:
“If This Fixed Order departs from before Me,” declares the LORD, “Then the offspring of Israel also will cease From being a nation before Me forever.” Thus says the LORD, “ If the heavens above can be measured And the foundations of the earth searched out below, Then I will also cast off all the offspring of Israel For all that they have done,” declares the LORD.
