Midrash su Salmi 106:8

Moses was keeping the flock. Though the time for their redemption was at hand, they had not as yet performed any meritorious deeds. Scripture declares this through the words of Ezekiel: I caused thee in increase even as the growth of the field … thy breasts were fattened, and thy hair was grown, yet thou wast naked and bare (Ezek. 16:7). Is it not so that the Holy One, blessed be He, would not have written breasts and hair except for the fact that breasts and hair allude to Moses and Aaron? Inasmuch as it is said concerning them: Thy two breasts are like two fawns, that are twins of a gazelle (Song 4:5). Thy hair was grown implies that the time for redemption had arrived, but naked and bare signify that Israel had not yet performed any good deeds. The verse For thy love is better than wine (ibid. 1:2) refers to the patriarchs, who are called beloved. And God heard their groaning, and remembered His covenant with Abraham, with Isaac, and with Jacob. And God saw the children of Israel (Exod. 2:24). That is, though He saw that they had not yet performed any meritorious deeds, He redeemed them nevertheless, as is said: He saved them for His name’s sake (Ps. 106:8).

"Praise the Lord, for He is good; His steadfast love is eternal." Thus let the redeemed of the Lord say, those He redeemed from adversity" (Psalms 107:1-2). This accords with what is stated in Scripture, "For My sake, My own sake, do I act--Lest [My Name] be dishonored" (Isaiah 48:11). He does not say "for My sake" once but "for My sake, for My sake" twice. The Holy Blessed One said, 'I am doing this only so that My Name not be profaned.' Why [is it written] twice, "for My sake, for My sake"? The Holy Blessed One said, 'when you were in Egypt, I redeemed you for the sake of My name, "He saved them for the sake of His name"' (Psalms 106:8). Similarly with [the future redemption from] Edom [, that is, from the control of the Roman Empire and its Christian successors], I will act for the sake of My name. ...
