▼tn Heb “do not approach a woman.” The phrase with נָגַשׁ (nagash, “approach”) is an idiom for sexual relations, which is also true of similar verbs such as בּוֹא אֶל (boʾ ʾel, “come to”) and קָרַב (qarav, “approach”). NIV “Abstain from sexual relations.” NASV “Do not go near a woman.” Temporary abstinence was also part of the prescribed practice for war efforts because the Lord would be in their camp (Deut 23:9-14).

▼sn B. Jacob (Exodus, 537) notes that as the people were to approach him they were not to lose themselves in earthly love. Such separations prepared the people for meeting God. Sinai was like a bride, forbidden to anyone else. Abstinence was the spiritual preparation for coming into the presence of the Holy One.
