לָכֵ֣ן יִתְּנֵ֔ם עַד־עֵ֥ת יוֹלֵדָ֖ה יָלָ֑דָה וְיֶ֣תֶר אֶחָ֔יו יְשׁוּב֖וּן עַל־בְּנֵ֥י יִשְׂרָאֵֽל׃
Mas tu, Belém Efrata, posto que pequena para estar entre os milhares de Judá, de ti é que me sairá aquele que há de reinar em Israel, e cujas saídas são desde os tempos antigos, desde os dias da eternidade.
Rashbam
כעת חיה, she would give birth at the appropriate time. The word appears in this context in Michah 5,2 כעת יולדה בן,”until she who is to bear has given birth.” It is also found describing the state of Jewish mothers giving birth as being equivalent to that of midwives. (Exodus 1,19)
