Deuteronomy 11:10
For the land, whither thou goest in to possess it, is not as the land of Egypt, from whence ye came out, where thou sowedst thy seed, and wateredst it with thy foot, as a garden of herbs: For the land, whither thou goest in to possess it, is not as the land of Egypt, from whence ye came out, where thou sowedst thy seed, and wateredst it with thy foot, as a garden of herbs:
The land Israel was about to enter to possess was not like the land of Egypt from which they had come out, and this contrast was set before them in Moses' rehearsal to the people before they entered Canaan, spoken during the wilderness wandering to guide them to the land they were soon to possess on condition of obedience to God's law. In Egypt sown seed was watered as a garden of herbs by laborious foot-operated machinery carrying water from the river. By contrast the promised land was hills and valleys drinking water of the rain of heaven, a land the Lord cares for with His eyes always upon it from the beginning of the year even to the end of the year, so that Israel need never suffer for lack of rain.
This difference presented Canaan as an advantage over Egypt and gave abundant occasion for rejoicing, for it was a good land flowing with milk and honey, with brooks of water, fountains and depths springing out of valleys and hills, wheat and barley and vines and fig trees and pomegranates, oil olive and honey, where bread would be eaten without scarceness and nothing would be lacked, whose stones are iron and out of whose hills brass may be dug. The contrast introduced a conditional promise that if Israel would hearken diligently to His commandments, love the Lord and serve Him with all heart and soul, He would give the first rain and the latter rain in due season to produce flourishing vegetation, so they might gather corn, wine and oil and have grass in the fields for cattle so they might eat and be full. But if their hearts were deceived to turn aside to serve and worship other gods, the Lord's wrath would shut heaven so there would be no rain, the land would not yield its fruit, and they would perish quickly from the good land.
The description of the land's blessings was meant to move the hearts of Israel as they remembered that Moses who pictured its blessings had through their sin been shut out from sharing the inheritance. The lessons of the eighth and eleventh chapters of Deuteronomy to which the verse belongs are of the greatest importance now and are given as verily to God's people today as to Israel, setting obedience to God's commandments as the way of blessing and turning aside to go after other gods as the way of curse. This was shown when disobedience was followed by the death of all but two of the adults who left Egypt before entering Canaan.
