Note this very carefully:
Isa 24:5 The earth also is defiled under the inhabitants thereof; because they have transgressed the laws, changed the ordinance [H2706 - choq = set time, Job 14:13], broken the everlasting [H5769 - ‘owlam] covenant.
Isa 24:6 Therefore hath the curse devoured the earth, and they that dwell therein are desolate: therefore the inhabitants of the earth are burned, and few men left.
Jer 44:22 So that the LORD could no longer bear, because of the evil of your doings, and because of the abominations which ye have committed; therefore is your land a desolation, and an astonishment, and a curse, without an inhabitant, as at this day.
Jer 44:23 Because ye have burned incense, and because ye have sinned against the LORD, and have not obeyed the voice of the LORD, nor walked in his law, nor in his statutes [H2708 - chuqqah = appointed], nor in his testimonies; therefore this evil is happened unto you, as at this day.
It is a transgression of the law of God, a changing of God’s law that breaks the everlasting covenant, that brings desolation. So just what is the everlasting covenant?
The Everlasting / Perpetual Covenant
Psa 111:7 The works of his hands are verity and judgment; all his commandments are sure.
Psa 111:8 They stand fast for ever and ever [H5769 - ‘owlam]: holy and reverend is his name.
Deu 4:12 And the LORD spake unto you out of the midst of the fire: ye heard the voice of the words, but saw no similitude; only ye heard a voice.
Deu 4:13 And he declared unto you his covenant, which he commanded you to perform, even ten commandments; and he wrote them upon two tables of stone.
Psa 103:18 To such as keep his covenant, and to those that remember his commandments to do them.
Psa 103:19 The LORD hath prepared his throne in the heavens; and his kingdom ruleth over all.
Exo 31:16 Wherefore the children of Israel shall keep the sabbath, to observe the sabbath throughout their generations, for a perpetual [H5769 - ‘owlam] covenant.
Exo 31:17 It is a sign between me and the children of Israel for ever [H5769 - ‘owlam]: for in six days the LORD made heaven and earth, and on the seventh day he rested, and was refreshed.
Isa 56:6 Also the sons of the stranger, that join themselves to the LORD, to serve him, and to love the name of the LORD, to be his servants, every one that keepeth the sabbath from polluting it, and taketh hold of my covenant;
Isa 56:7 Even them will I bring to my holy mountain, and make them joyful in my house of prayer: their burnt offerings and their sacrifices shall be accepted upon mine altar; for mine house shall be called an house of prayer for all people.
The everlasting or perpetual covenant of Isaiah 24:5 is identified in Exodus 31:16 as the Sabbath commandment of God’s law. Changing that commandment so as to break it, brings desolation according to Isaiah 24:6.
