"He shall deliver the island of the innocent" (Job 22:30) — one measure [unkiya] in the hand of Noah. If so, why "shall be delivered"? Rather, "it is delivered by the cleanness of your hands" — that you found grace. Three discoveries the Holy One, blessed be He, made: "And You found his heart faithful before You" (Nehemiah 9:8) [of Abraham]; "I have found David My servant" (Psalms 89:21); "Like grapes in the wilderness I found Israel" (Hosea 9:10). But is it not written, "And Noah found grace"? He said to him: he found, but the Holy One, blessed be He, did not [reckon it among His own discoveries]. To one who was on the road and saw another and they became attached — how far? Until he bound love with him. It is said here "grace," and it is said there, "And Joseph found grace" (Genesis 39:4) [a verbal analogy].
Noah Found Grace and the Three Discoveries of the Holy One
Yalkut Shimoni on Torah 47:3
יְמַלֵּט אִי נָקִי אוּנְקִיָּא אַחַת בְּיַד נֹחַ, אִם כֵּן לָמָּה "נִמְלַט" אֶלָּא "בְּבֹר כַּפֶּיךָ" שֶׁמָּצָאתָ חֵן. שְׁלֹשָׁה מְצִיאוֹת מָצָא הַקָּדוֹשׁ בָּרוּךְ הוּא. (נחמיה ט, ח) "וּמָצָאתָ אֶת לְבָבוֹ נֶאֱמָן לְפָנֶיךָ", (תהלים פט, כא) "מָצָאתִי דָּוִד עַבְדִּי", "כַּעֲנָבִים בַּמִּדְבָּר מָצָאתִי יִשְׂרָאֵל". וְהָכְתִיב וְנֹחַ מָצָא חֵן, אָמַר לֵיהּ, הוּא מָצָא וְהַקָּדוֹשׁ בָּרוּךְ הוּא לֹא מָצָא לְאֶחָד שֶׁהָיָה בַּדֶּרֶךְ וְרָאָה אֶחָד וְדָבְקוּ, עַד הֵיכָן, עַד דְּקָשַׁר עִמּוֹ אַהֲבָה נֶאֱמַר כַּאן חֵן וְנֶאֱמַר לְהַלָּן (בראשית לט, ד) "וַיִּמְצָא יוֹסֵף חֵן".
