2 Corinthians 3:11, Passing away. This is not a reference to the Torah-law itself, but to the old or former covenant (i.e., the agreement or contract YHVH and Israel made with each other) as it phases into the new or renewed covenant.
Yeshua initiated the new covenant at his last supper, but it will be finalized with the two houses of Israel (see Jer 31:31, 33 and Heb 8:8) at his second coming when the two sticks or houses of Israel are reunited (see Ezek 37:15–27) at which time he will finalize the new covenant with a reunited Israel (v. 26; see also Isa 54:10; 55:3; 59:21; Ezek 34:25; Jer 32:40; 50:5; Hos 2:18–23).
We are presently in the intermediate phase between the two covenants. To view it from a different perspective, Yeshua betrothed himself to his spiritual bride (redeemed Israel, spiritual Israel or the Israel of Elohim, see Gal 6:16) at his last supper, but will marry her at his second coming. The saints who are now in Yeshua are under the new covenant as the betrothed bride of Yeshua, but all Israel will be brought into the new covenant at his second coming at which time he will finalize the covenant that he initiated with his disciples before his death.
