Midrash Aggadah, Genesis 24:50

"From the LORD the matter has come forth" (Genesis 24:50) — from the fact that the land leapt for you, and furthermore that the condition which you stated came about for you; therefore "we cannot speak to you" and so forth (Genesis 24:50). From here our Sages, of blessed memory, said: From the LORD [comes] a wife for a man. And this matter is written in the Torah, as it is said, "From the LORD the matter has come forth." And furthermore it is threefold, [stated also] in the Prophets and in the Writings. In the Prophets: "and his father and his mother did not know that it was from the LORD" (Judges 4:4). In the Writings: "and from the LORD [comes] a prudent wife" (Proverbs 14:4).
