The Land To Which They Are Going Is An Abundant Land. It Is Watered By God And Is Dependent On His Care, A Care Dependent On Their Obedience To The Covenant Requirements (Deuteronomy 11:10-17).
Analysis in the words of Moses:
a For the land, to which you are going in to possess it, is not as the land of Egypt, from where you came out, where you sowed your seed, and watered it with your foot, as a garden of herbs (Deuteronomy 11:10).
b But the land to which you are going over to possess it, is a land of hills and valleys, and drinks water of the rain of heaven (Deuteronomy 11:11).
b A land which Yahweh your God cares for (Deuteronomy 11:12 a).
a The eyes of Yahweh your God are always on it, from the beginning of the year even to the end of the year (Deuteronomy 11:12 b).
Note that in ‘a' the land that they are going over to possess is not a land which they will have to toil hard on, for in the parallel it is one on which Yahweh's eyes are permanently set, from the beginning to the end of the year. In ‘b' it is a land fed by wateer from heaven, and in the parallel is a land that Yahweh their God cares for.
‘ For the land, to which you (thou) are going in to possess it, is not as the land of Egypt, from where you (ye) came out, where you (thou) sowed your (thy) seed, and watered it with your foot, as a garden of herbs,'
For they were going to a far, far better land than the one from which they had come out. The land to which they are going is not like Egypt, the land which they had left. That was a flat land, and there they sowed their seed, and then had to keep it watered by building irrigation channels, and laboriously working equipment with their feet to bring the water to the land, as they would water a garden of herbs. They would then use their feet again to open and block small channels around their land. It all required constant effort. ‘A garden of herbs' stressed the effort that had to be put in, and the fruitful result that followed, for the maintenance of such gardens required great effort.
Egypt enjoyed the blessing that the Nile rose and covered parts of their land every year, renewing the land, but it then fell, and they had to work hard to ensure that they made the best use of its waters. It required constant effort. The point is being made that the watering there was a result of man's physical activity and exertions. They would remember only too well those activities and exertions in which they had had to engage, no doubt even as children.
‘ But the land to which you (ye) are going over to possess it, is a land of hills and valleys, and drinks water of the rain of heaven, a land which Yahweh your (thy) God cares for. The eyes of Yahweh your (thy) God are always on it, from the beginning of the year even to the end of the year.'
But in the land to which they were now going, where water would be provided by God, it was not like that. It was to be a land of hills and valleys, a land that drank water that came from above (it did not need to be force fed), even the rain of heaven. It would receive water that fell where it was wanted, or flowed down to where it was wanted. And it was a land which Yahweh their God cared for continually, for His eyes were always on it, from the beginning of the year to the end of the year. So those who lived in it depended on His goodness for the provision of water, and when they were right with Him could be sure of that provision (except for occasional times of testing). Thus while Egypt depended on the Nile, they would rather depend directly on God, and while Egypt laboured to spread their waters Israel would receive God's blessing with joy.
And what was more God cared for this land especially, because it was the land that He had promised to Abraham, and He was keeping it for his descendants. It does not mean that God did not care for other lands, only that they did not come under His special care. Here God was intimately concerned for the sake of His people.
