[Chapter 37] Verse 36: And the Midianites sold him into Egypt unto Potiphar (Gen. 39:1), an officer (Heb. eunuch: but the word doth signify not only eunuchs, but also chamberlains, courtiers , and officers , Esther 1:10) of Pharaoh’s, and captain of the guard (Heb. chief of the slaughtermen, or, executioners ; or, chief marshal ).
[A eunuch, syrIs;] Such he was not properly, for he had a wife,3 and a daughter, who afterwards married Joseph4 (Fagius’ Comparison of the Principal Translations , Estius). But they are called eunuchs who used to be put in charge of duties in the palace (Tirinus); because perhaps most were eunuchs (Estius). Among Easterners, satraps were thus called (Vatablus).
[Chief of the soldiers, Myxib@f+@aha r#oa] Chief of the cooks 5 (Septuagint, Menochius), or, of the butchers (Pagnine, Montanus, Vatablus, Munster, Menochius, Rabbi Salomon in Fagius’ Comparison of the Principal Translations), for he would have been put in charge of the cooks and the slaughterers of cattle (Vatablus). This does not satisfy, for Nebuzaradan is called by this name, 2 Kings 25:8, 11, 20 (Castalio). Others: a prefect , or leader, of soldiers (thus the Chaldean, Arabic, Syriac). Prefect of the bodyguards (de Dieu after Vatablus). This is gathered from chapter 40. See Jeremiah 39:9 (Vatablus). Warden of the royal house , or person (Oleaster); master of the army of that one (Tirinus). Not of the entire army, but of the bodyguards (Vatablus). He was named from slaughtering , perhaps because he inflicted punishments upon criminals (Castalio). Prefect of capital cases (Tigurinus).
Whose office it was to apprehend and punish criminal persons. See Genesis 40:3; Jeremiah 39:9; Mark 6:27.
