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).
