Commentary for Job 20:29

appointed him by God Heb. אִמְרוֹ. What was said about him from before the Omnipresent. The word אִמְרוֹ is in the masculine gender, from the form of (Ps. 5:2), “Give ear to my words (אַמָרַי).” אִמְרָתוֹ appears (ibid. 147:15) in the feminine gender, from the form of (ibid. 12:7) “pure words (אַמָרוֹת).”
