Midrash sobre Cantar de los Cantares 7:13

“Let us arise early to the vineyards; let us see whether the vine has blossomed, the grape bud has sprouted, the pomegranates have bloomed; there I will give my love to you” (Song of Songs 7:13).
“Let us arise early to the vineyards,” these are Israel, as it is stated: “For the house of Israel is the vineyard of the Lord of hosts” (Isaiah 5:7). “Let us see whether the vine has blossomed,” this is the reciting of Shema; “the grape bud has sprouted,” these are the synagogues and the study halls; “the pomegranates have bloomed,” these are the children who sit and engage in Torah study. “There I will give my love,” there I will develop the righteous men and women, and the prophets and prophetesses who emerge from them.
