Hired men. This is a further reference to the mercenaries who played a prominent role in the Egyptian army during this period (see on vs. 9, 16).
Visitation. From the Heb. paqad, meaning basically, “to visit,” but used frequently in the sense of visiting with punishment (see Ex. 20:5; Job 35:15; Ps. 59:5; Isa. 26:14; Jer. 14:10). “Time of their visitation,” “year of their visitation,” are favorite expressions with Jeremiah (see chs. 8:12; 10:15; 11:23; 23:12; 48:44; 50:27; 51:18). However, paqad may also mean to visit with a divine blessing (see Gen. 21:1; Ps. 80:14). Jehovah’s day of visitation upon Egypt was not only a punishment but also a call to rectitude of action and repentance of heart (see Jer. 46:28).
