אַֽל־תִּזְכְּר֖וּ רִֽאשֹׁנ֑וֹת וְקַדְמֹנִיּ֖וֹת אַל־תִּתְבֹּנָֽנוּ׃
Не помни прежних вещей и не думай о старом.
Rashi
Remember not the first events These miracles that I mention to you, that I performed in Egypt do not remember them from now on, for you shall be engaged in this redemption, to thank and to praise.
Rashi
do not meditate Do not ponder about them; do not pay attention to them.
