Paul’s message, that Yeshua was the Messiah sent from YHVH to regather the dispersed tribes of Israel and restore both houses of Israel and Judah in the Land of Israel (Isa 11:10-16; Eze 37:15-28) was an izmail (a metal knife used to perform circumcision; sharp on both edges, see Jsh 5:2). One edge of the izmail would cut the covenant and allow the lost Israelites to reenter the Commonwealth of Israel (Eph 2:12-13). The other edge would disqualify (Deu 23:1) Israel's enemies.
2Cor 2:14-16 Now thanks be unto YHVH, who always causes us to triumph in the Messiah of Israel, and makes manifest the odor of His knowledge by us in every place. For we are unto YHVH a sweet odor of the Messiah of Israel, in them that are saved (descendants of Jacob, Rom 9:21), and in them that perish (descendants of Esau, Rom 9:22). To the one we are the odor of death unto death (Isa 26:14, Jer 51:57; Mal 1:3-4; 1The 4:13) and to the other the odor of life unto life (Mal 4:1-3). And who is sufficient for these things?
Financial incentive does not make Paul sufficient for these things.
2Cor 2:17 For we are not as many, who peddle the Word of YHVH, but as of sincerity, but as of YHVH, in the sight of YHVH speak we in the Messiah of Israel.
Commendation does not make Paul sufficient.
2Cor 3:1-3 Do we begin again to commend ourselves? Or do we need, as some others, letters of commendation to you, or letters of commendation from you? Ye are our letter of commendation written in our hearts, known and read of all men; forasmuch as ye are manifestly declared to be the letter from the Messiah of Israel served by us, written not with ink, but with the spirit (authenticity) of the living Elohim; not on a molding board (used to knead dough) made of stone, but on a molding board made of flesh, on hearts (Pro 7:1-3).
Paul was made sufficient by YHVH.
