Numbers 7:12

ביום הראשון ON THE FIRST DAY — That day received ten crowns (was distinguished in ten different ways): it was the same day as was the first day of Creation, the first day on which the princes offered etc., as it is set forth in Seder Olam 7 (cf. Rashi on Leviticus 9:1 and Note 2 thereon). למטה יהודה [NACHSHON THE SON OF AMINADAB,] OF THE TRIBE OF JUDAH — By these words Scripture merely states his genealogy after his tribe, and they do not mean that he collected the offerings from his tribe and offered them on their behalf. Or perhaps it does state למטה יהודה only to intimate that he collected the offerings from his tribe and then brought them? Scripture, however, states, (v. 17): this was the offering of Nachshon — he brought it of that which was his own (Sifrei Bamidbar 48).

And he that offered his offering the first day was Naĥshon the son of ῾Amminadav, of the tribe of Yehuda:
