וַיֹּ֣אמְר֔וּ אֱלֹהֵ֥י הָעִבְרִ֖ים נִקְרָ֣א עָלֵ֑ינוּ נֵ֣לֲכָה נָּ֡א דֶּרֶךְ֩ שְׁלֹ֨שֶׁת יָמִ֜ים בַּמִּדְבָּ֗ר וְנִזְבְּחָה֙ לַֽיהוָ֣ה אֱלֹהֵ֔ינוּ פֶּ֨ן־יִפְגָּעֵ֔נוּ בַּדֶּ֖בֶר א֥וֹ בֶחָֽרֶב׃
Mereka berkata, “Allah orang Ibrani telah menjumpai kami. Izinkanlah kami pergi sejauh perjalanan tiga hari ke padang gurun untuk mempersembahkan kurban kepada Yang Mahakekal, Allah kami, supaya Ia tidak menimpa kami dengan penyakit sampar atau dengan pedang.”
Rashi
פן יפגענו LEST HE LIGHT ON US — They should have said, “Lest He light on thee (Pharaoh) [with pestilence] etc.” — but they showed respect to royalty (the king) by thus expressing themselves. This term פגיעה “lighting on”, “meeting” denotes meeting with death (Exodus Rabbah 5:15).
Chizkuni
ויאמרו: אלוקי העברים, they said in response to Pharaoh denying that there was a G-d called Hashem (or a people called Israel), that they were talking about the G-d of the Hebrews. The G-d of the Hebrews sits in judgment of His people as He is their G-d and are His servants and His people.”
Da'at Zekenim
דרך שלשת ימים, “a distance of three days’ walk.” The plain meaning of the verse is that Moses requested to take the people to the desert in order there to offer sacrifices to their G–d. In the event that Pharaoh would ask: “why can you not offer these sacrifices right here?” Moses anticipated this question, and he added that unless we do it in the desert we will be subject to severe punishment by our G–d. (Compare Exodus 8,22 for further elaboration)
