Deuteronomy 18:5
JPS-1917כִּ֣י ב֗וֹ בָּחַ֛ר יְהֹוָ֥ה אֱלֹהֶ֖יךָ מִכׇּל־שְׁבָטֶ֑יךָ לַעֲמֹ֨ד לְשָׁרֵ֧ת בְּשֵׁם־יְהֹוָ֛ה ה֥וּא וּבָנָ֖יו כׇּל־הַיָּמִֽים׃ {ס}
For the LORD thy God hath chosen him out of all thy tribes, to stand to minister in the name of the LORD, him and his sons for ever.
Rashi Commentary
לעמד לשרת TO STAND TO MINISTER — From here we may derive the law that the sacrificial service must be performed standing (Sifrei Devarim 167:1; Sota 38a).
