There shall nothing cast their young, nor be barren - Hence there must be a very great increase both of men and cattle.

The number of thy days I will fulfill - Ye shall all live to a good old age, and none die before his time. This is the blessing of the righteous, for wicked men live not out half their days; Psalm 55:23.

There shall nothing cast their young, nor be barren in the land,.... There shall be no abortions or miscarriages, nor sterility or barrenness, either among the Israelites, or their cattle of every kind, so that there should be a great increase, both of men and beasts:

the number of thy days I will fulfil; which was fixed for each of them, in his eternal purposes and decrees; or what, according to the temperament of their bodies and the course of nature, which, humanly speaking, it might be supposed they would arrive unto; or generally the common term of human life, which, in the days of Moses, was threescore years and ten, or fourscore, see Job 14:5, it may be considered whether any respect is had to the time of their continuance in the land of Canaan, the term of which was fixed in the divine mind, or the fulness of time in which the Messiah was to come.

There shall nothing cast their young, nor be barren, in thy land: the number of thy days I will fulfil.

23:26 The number of thy days I will fulfill - And they shall not be cut off in the midst by untimely deaths. Thus hath godliness the promise of the life that now is.

23:20-33 It is here promised that they should be guided and kept in their way through the wilderness to the land of promise, Behold, I send an angel before thee, mine angel. The precept joined with this promise is, that they be obedient to this angel whom God would send before them. Christ is the Angel of Jehovah; this is plainly taught by St. Paul, 1Co 10:9. They should have a comfortable settlement in the land of Canaan. How reasonable are the conditions of this promise; that they should serve the only true God; not the gods of the nations, which are no gods at all. How rich are the particulars of this promise! The comfort of their food, the continuance of their health, the increase of their wealth, the prolonging their lives to old age. Thus hath godliness the promise of the life that now is. It is promised that they should subdue their enemies. Hosts of hornets made way for the hosts of Israel; such mean creatures can God use for chastising his people's enemies. In real kindness to the church, its enemies are subdued by little and little; thus we are kept on our guard, and in continual dependence on God. Corruptions are driven out of the hearts of God's people, not all at once, but by little and little. The precept with this promise is, that they should not make friendship with idolaters. Those that would keep from bad courses, must keep from bad company. It is dangerous to live in a bad neighbourhood; others' sins will be our snares. Our greatest danger is from those who would make us sin against God.
