Numbers 28:4

את הכבש אחד THE ONE LAMB [SHALT THOU OFFER IN THE MORNING] — Although it has already been stated in the section beginning with the words ,ואתה תצוה (Exodus 29:38 39): “Now this is what thou shalt offer … [The one lamb thou shalt offer in the morning]”, that was an instruction for the days of the installation ceremony of the priests, but here it states the commands for all generations.

אֶת־הַכֶּ֥בֶשׂ אֶחָ֖ד תַּעֲשֶׂ֣ה בַבֹּ֑קֶר וְאֵת֙ הַכֶּ֣בֶשׂ הַשֵּׁנִ֔י תַּעֲשֶׂ֖ה בֵּ֥ין הָֽעַרְבָּֽיִם׃

The one lamb shalt thou offer in the morning, and the other lamb shalt thou offer at evening;
