Verse 11: (Ecclus. 46:9; see Deut. 34:7) As yet I am as strong this day as I was in the day that Moses sent me: as my strength was then, even so is my strength now, for war, both (Deut. 31:2) to go out, and to come in.
[As strong, etc.] כ repeated means as, and thus/so (Drusius).
[As much to fight, etc.] Hebrew: to go out and to come in (Masius, Septuagint). In going out and coming in; in attending to all the duties of war (Drusius). See 1 Samuel 18:5. Rather, to come in and go out is to fulfill one’s office in every duty of life. He signifies in these words that he seeks nothing unsuitable for his age, although he entreats an arduous duty for himself (Masius). To go out, etc., that is, to undertake a journey: in French, à aller et venir, to come and go (Vatablus). To attend to business, both public and domestic; for the former of which it is necessary to go out from the house, but for the latter it is necessary to enter into the same. It is Metonymy of intended effect (Piscator). God gave this vigor to him, both for a reward of his fidelity, so that he, yet vigorous and strong, might take possession of the Promised Land; and so that he might be an eye-witness of all that happened in the desert, and relate those things to those younger (Lapide).
For war; not only for counsel, but for action, for marching and fighting. And therefore this gift will not be cast away upon an unprofitable and unserviceable person. To go out, and to come in; to perform all the duties belonging to my place.
