קְדֹשִׁ֤ים יִהְיוּ֙ לֵאלֹ֣הֵיהֶ֔ם וְלֹ֣א יְחַלְּל֔וּ שֵׁ֖ם אֱלֹהֵיהֶ֑ם כִּי֩ אֶת־אִשֵּׁ֨י יְהוָ֜ה לֶ֧חֶם אֱלֹהֵיהֶ֛ם הֵ֥ם מַקְרִיבִ֖ם וְהָ֥יוּ קֹֽדֶשׁ׃
Sila ay magiging banal sa kanilang Diyos, at hindi nila lalapastanganin ang pangalan ng kanilang Diyos; sapagkat ang mga handog na pinaraan sa apoy para sa Walang-Hanggan, ang tinapay ng kanilang Diyos, ang siyang inihahandog nila; at sila ay magiging banal.
Rashi
קדשים יהיו THEY SHALL BE HOLY — even against their will — the court shall force them to remain holy in respect to this (Sifra, Emor, Chapter 1 6).
Ibn Ezra
so that they will not desecrate the Name of their God which they are liable to do when they offer up the fire-offering of God.
Ramban
THEY SHALL BE HOLY UNTO THEIR G-D. Holiness signifies separateness, as I have explained in the section above.24In the beginning of Seder Kedoshim. Scripture is thus stating that even in those things which are permissible to Israelites, the priests should exercise self-control, avoiding the impurity of the dead, and marrying of women who are unfit for them in purity and cleanliness.
