Exodus 29:1

לקח This is the same as קח (the imperative, “Take thou” and must not be regarded as the infinitive). There are two forms of the root: one is קח and the other לקח, both having the same meaning. פר אחד ONE BULLOCK — to atone for the incident of worshipping the golden calf which is of the bullock species (cf. Sifra on Leviticus 9:2).

And this is the thing that thou shalt do to them to hallow them, to minister to me in the priest’s office: Take one young bullock, and two rams without blemish,

וְזֶ֨ה הַדָּבָ֜ר אֲשֶֽׁר־תַּעֲשֶׂ֥ה לָהֶ֛ם לְקַדֵּ֥שׁ אֹתָ֖ם לְכַהֵ֣ן לִ֑י לְ֠קַ֠ח פַּ֣ר אֶחָ֧ד בֶּן־בָּקָ֛ר וְאֵילִ֥ם שְׁנַ֖יִם תְּמִימִֽם׃
