וַיְהִ֥י בַדֶּ֖רֶךְ בַּמָּל֑וֹן וַיִּפְגְּשֵׁ֣הוּ יְהוָ֔ה וַיְבַקֵּ֖שׁ הֲמִיתֽוֹ

At a night encampment on the way, the LORD encountered him and sought to kill him.

וַתִּקַּ֨ח צִפֹּרָ֜ה צֹ֗ר וַתִּכְרֹת֙ אֶת־עָרְלַ֣ת בְּנָ֔הּ וַתַּגַּ֖ע לְרַגְלָ֑יו וַתֹּ֕אמֶר כִּ֧י חֲתַן־דָּמִ֛ים אַתָּ֖ה לִֽי

So Zipporah took a flint and cut off her son’s foreskin, and touched his legs with it, saying, “You are truly a bridegroom of blood to me!” 

וַיִּ֖רֶף מִמֶּ֑נּוּ אָ֚ז אָֽמְרָ֔ה חֲתַ֥ן דָּמִ֖ים לַמּוּלֹֽת

And when He let him alone, she added, “A bridegroom of blood because of the circumcision.” 

Exodus 4: 24-26
