Ibn Ezra on Leviticus 16:10

יעמד חי. מהבנין הכבד הנוסף שלא נזכר שם פועלו והיה היו״ד ראוי להיותו מאוסף בשור״ק רק נרחב בעבור אות הגרון וכן יחרם כל רכושו: SHALL BE SET ALIVE. The word yo’omad (shall be set) is a hofal.⁵⁶Literally, from the heavy conjugation which has a word added to it and whose subject is not mentioned. The yod⁵⁷Prefixed to the root. should have been vocalized with a shuruk.⁵⁸A kubbutz, for that is the way words in the imperfect are conjugated in the hofal. Compare, yuktzar, yurad However, it was enlarged⁵⁹It was enlarged from a minor vowel (a kubbutz) to a major vowel (a kamatz). because of the guttural.⁶⁰The ayin, for the root of yo’omad is ayin, mem, dalet. The word yochoram (should be forfeited) in all his substance should be forfeited (Ez. 10:8) is similar.⁶¹It too is vocalized with a kamatz rather than with a kubbutz because of its guttural.

לכפר עליו. כי הכפור יהי עליו ופירושו לשלח אותו: TO MAKE ATONEMENT OVER HIM.⁶²Over it, over the goat. For the atonement shall be upon it.⁶³The sins will be placed upon the goat, who shall remove the sins by carrying them into the wilderness. It means to send him away.
