וַיֹּ֨אמֶר יְהוָ֜ה לָ֗הּ שְׁנֵ֤י גיים [גוֹיִם֙] בְּבִטְנֵ֔ךְ וּשְׁנֵ֣י לְאֻמִּ֔ים מִמֵּעַ֖יִךְ יִפָּרֵ֑דוּ וּלְאֹם֙ מִלְאֹ֣ם יֶֽאֱמָ֔ץ וְרַ֖ב יַעֲבֹ֥ד צָעִֽיר׃
여호와께서 그에게 이르시되 두 국민이 네 태중에 있구나 두 민족이 네 복중에서부터 나누이리라 이 족속이 저 족속보다 강하겠고 큰 자는 어린 자를 섬기리라 하셨더라
Rashi on Genesis
ויאמר ה' לה AND THE ETERNAL SAID UNTO HER through a messenger: it was told to Shem by holy inspiration and he told it to her (Genesis Rabbah 63:7).
Ramban on Genesis
TWO NATIONS ARE IN THY WOMB. The intent of this is that He informed her that she should not fear, for the reason that the struggle in her womb is that she is pregnant with twins, this being the customary way among women who are pregnant with twins.
It is possible that He is also saying that since they are destined to be two peoples, hating and warring with each other, at the very beginning of their creation they initiated a quarrel, thus intimating at the situation which will ultimately exist between them. But He assured her that now they will rest, and she will find rest and quiet for herself.

Radak on Genesis
ויאמר ה' לה, by means of the prophet who was either Shem or Avraham.
