Bamidbar 28:3

ואמרת להם AND THOU SHALT SAY TO THEM — This is an instruction to the Beth Din (Sifrei Bamidbar 142:3). שנים ליום This may be understood according to its plain sense: TWO [LAMBS] FOR EACH DAY, But in the main it is intended to teach that they should be slaughtered at a spot opposite the day (i.e. the sun) — the morning continual offerings at the west and that of the evening at the east of the rings fixed in the ground and in which were inserted the animals feet (Sifrei Bamidbar 142:3; Yoma 62b).

וְאָמַרְתָּ֣ לָהֶ֔ם זֶ֚ה הָֽאִשֶּׁ֔ה אֲשֶׁ֥ר תַּקְרִ֖יבוּ לַיהֹוָ֑ה כְּבָשִׂ֨ים בְּנֵֽי־שָׁנָ֧ה תְמִימִ֛ם שְׁנַ֥יִם לַיּ֖וֹם עֹלָ֥ה תָמִֽיד׃

And thou shalt say to them, This is the fire offering which you shall offer to the Lord; two lambs of the first year without blemish day by day, for a continual burnt offering.
