שָׁמוֹר֙ אֶת־חֹ֣דֶשׁ הָאָבִ֔יב וְעָשִׂ֣יתָ פֶּ֔סַח לַיהוָ֖ה אֱלֹהֶ֑יךָ כִּ֞י בְּחֹ֣דֶשׁ הָֽאָבִ֗יב הוֹצִ֨יאֲךָ֜ יְהוָ֧ה אֱלֹהֶ֛יךָ מִמִּצְרַ֖יִם לָֽיְלָה׃
Observe the month of Abib, and keep the passover unto the LORD thy God; for in the month of Abib the LORD thy God brought thee forth out of Egypt by night.
Targum Jonathan on Deuteronomy
Be mindful to keep the times of the festivals, with the intercalations of the year, and to observe the rotation thereof: in the month of Abiba to perform the pascha before the Lord your God, because in the month of Abiba the Lord your God brought you out of Mizraim; you shall eat it therefore by night.
