Kehillah in Galatia 3:17-19

Orthodox Jewish Bible

¹⁷ And this I say: a brit (covenant), which was previously confirmed by Hashem, cannot be annulled so as to abolish the havtachah (promise) by the Mattan Torah‖which was given arba me’ot usheloshim shanah [four hundred and thirty years later SHEMOT 12:40]).

¹⁸ For if the nachalah (inheritance) is based on Torah, it is no longer based on havtachah (promise); but Hashem has given the nachalah to Avraham Avinu by havtachah (promise).

¹⁹ Why then the Mattan Torah (Giving of the Torah)? The Torah was added because of peysha’im, until the ZERA (Moshiach) should come to whom the havtachah had been made (BERESHIS 22:18). Now the Torah was administered through malachim (DEVARIM 33:2; TEHILLIM 68:18) by the hand of a metavech (VAYIKRA 26:46; BAMIDBAR 36:13).
