וַיֹּ֣אמֶר לִ֔י הִנָּ֥ךְ הָרָ֖ה וְיֹלַ֣דְתְּ בֵּ֑ן וְעַתָּ֞ה אַל־תִּשְׁתִּ֣י ׀ יַ֣יִן וְשֵׁכָ֗ר וְאַל־תֹּֽאכְלִי֙ כָּל־טֻמְאָ֔ה כִּֽי־נְזִ֤יר אֱלֹהִים֙ יִהְיֶ֣ה הַנַּ֔עַר מִן־הַבֶּ֖טֶן עַד־י֥וֹם מוֹתֽוֹ׃ (פ)
Ngunit sinabi niya sa akin: ‹Narito, ikaw ay maglilihi at manganganak ng isang lalaki; kaya ngayon, huwag kang iinom ng alak o ng anumang inuming nakalalasing, at huwag kang kakain ng anumang bagay na marumi, sapagkat ang bata ay magiging nazir ng Diyos mula pa sa sinapupunan hanggang sa araw ng kanyang kamatayan.›”
Rashi
הנך הרה BEHOLD THOU WILT BE WITH CHILD — when you return you will conceive, just as the same phrase הנך הרה (Judges 13:7) spoken of the wife of Manoah (where it certainly appears to be thou wilt conceive in the future).
