This is the observable night of the Lord, when he brought them forth out of the land of Egypt: this night all the children of Israel must observe in their generations.
לֵ֣יל שִׁמֻּרִ֥ים הוּא֙ לַֽיהוָ֔ה לְהוֹצִיאָ֖ם מֵאֶ֣רֶץ מִצְרָ֑יִם הֽוּא־הַלַּ֤יְלָה הַזֶּה֙ לַֽיהוָ֔ה שִׁמֻּרִ֛ים לְכָל־בְּנֵ֥י יִשְׂרָאֵ֖ל לְדֹרֹתָֽם׃

Those who partook of the lamb were instructed to remain in solemn vigilance throughout the night. In a similar manner, we are called to remain alert regarding the profound act of our salvation, in line with the apostle's exhortation: Be watchful, vigilant, etc. 1 Pet. 5:8.
