David didn't believe the law was temporary.
Psalm 119:44
So shall I keep Your law continually, forever and ever.
Psalm 119:142
Your righteousness is an everlasting righteousness, And Your law is truth.
Since the law is truth, how is truth temporary? If you believe truth is temporary, then you must believe Jesus is temporary.
I believe the Bible teaches that the Old Law is no longer binding. For even certain moral laws had the death penalty attached to them. However, we are under the laws or commands in the New Testament, though.
But the Old Testament Law has been fulfilled.
For the word "forever" (and it's related words) does not always mean forever in the Bible. “Forever” can have a temporal sense. For what do you make of the following verses below that say that "forever" (or it's related words) is not forever?
• In Gen.13:15 the land of Canaan is given to Israel “forever”.
• The Law is to be a statute “forever” (Ex.12:24; 27:21; 28:43).
• Sodom's fiery judgment is "eternal" (Jude 7) until -- God "will restore the fortunes of Sodom" (Ezek.16:53-55).
• Israel's "affliction is incurable" (Jer.30:12) until -- the Lord "will restore health" and heal her wounds (Jer.30:17).
• The sin of Samaria "is incurable" (Mic.1:9) until -- Lord "will restore ... the fortunes of Samaria." (Ez.16:53).
• Ammon is to become a "wasteland forever" and "rise no more" (Zeph.2:9, Jer.25:27 until -- the Lord will "restore the fortunes of the Ammonites" (Jer.49:6).
• An Ammonite or Moabite is forbidden to enter the Lord's congregation "forever" until -- the tenth generation (Deut.23:3):
• Habakkuk tells us of mountains that were "everlasting" until -- they "were shattered" Hab.3 3:6).
• The Aaronic Priesthood was to be an "everlasting" priesthood (Ex.40:15), that is-until-it was superceded by the Melchizedek Priesthood (Heb.7:14-18).
• Many translations of the Bible inform us that God would dwell in Solomon's Temple "forever" (1 Kings 8:13), until -- the Temple was destroyed.
• The children of Israel were to "observe the Sabbath throughout their generations, for a perpetual covenant" (Exodus 31:16)-until -- Paul states there remains "another day" of Sabbath rest for the people of God (Heb. 4:8,9).
• The Law of Moses was to be an "everlasting covenant" (Lev.24:8) yet we read in the New Covenant the first was "done away" and "abolished" (2 Cor. 3:11,13), and God "made the first old" (Hebrews 8:13).
• The fire for Israel's sin offering (of a ram without blemish) is never to be put out. It shall be a "perpetual" until -- Christ, the Lamb of God, dies for our sins.
Hell. We now have a better covenant established on better promises (Lev. 6:12-13, Heb. 8:6-13).
• God's waves of wrath roll over Jonah "forever" until--the Lord delivers him from the large fish's belly on the third day (Jonah 2:6,10; 1: 17); Egypt and Elam will "rise no more" (Jer.25:27) until -- the Lord will "restore the fortunes of Egypt" (Ez.29:14) and "restore the fortunes of Elam" (Jer.49:39).
• "Moab is destroyed" (Jer.48:4, 42) until--the Lord "will restore the fortunes of Moab" (Jer.48:47).
• Israel's judgment lasts "forever" until -- the Spirit is poured out and God restores it (Isa.32:13-15).
• The King James Bible, as well as many others, tells us that a bond slave was to serve his master "forever" (Exodus 21:6), until -- his death.
• “Eternal” (Greek aionia, αιονια) is sometimes used of a limited (not endless) period of time. But the most common use is illustrated in II Cor.4:18 where it is contrasted with “temporal” and in Philemon 15 where it is contrasted with “for a while.”
