וַיֹּ֣אמְר֔וּ אֱלֹהֵ֥י הָעִבְרִ֖ים נִקְרָ֣א עָלֵ֑ינוּ נֵ֣לֲכָה נָּ֡א דֶּרֶךְ֩ שְׁלֹ֨שֶׁת יָמִ֜ים בַּמִּדְבָּ֗ר וְנִזְבְּחָה֙ לַֽיהוָ֣ה אֱלֹהֵ֔ינוּ פֶּ֨ן־יִפְגָּעֵ֔נוּ בַּדֶּ֖בֶר א֥וֹ בֶחָֽרֶב׃
그들이 가로되 히브리인의 하나님이 우리에게 나타나셨은즉 우리가 사흘길쯤 광야에 가서 우리 하나님 여호와께 희생을 드리려하오니 가기를 허락하소서 여호와께서 온역이나 칼로 우리를 치실까 두려워하나이다
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)
