“Abraham will become.” Rabbi Tanḥum in the name of Rabbi Berekhya: He informed him that the world would have no less than thirty righteous men like Abraham.17He derived this from the verse: “So shall be [yihye] your seed” (Genesis 15:5), yihye alluding to thirty, as the Midrash goes on to explain (Tanḥuma, Vayera 13). Rabbi Yudan and Rabbi Aḥa in the name of Rabbi Alexandri cite it from here: “Abraham will become [hayo yihye].” Yod is ten, heh is five, yod is ten, heh is five.18The numerical value of yihye is thirty.
