Leviticus 25:18

"Wherefore ye shall do my statutes, and keep mine ordinances and do them; and ye shall dwell in the land in safety. And the land shall yield its fruit, and ye shall eat your fill, and dwell therein in safety. And if ye shall say, What shall we eat the seventh year? behold, we shall not sow, nor gather in our increase; then I will command my blessing upon you in the sixth year, and it shall bring forth fruit for the three years. And ye shall sow the eighth year, and eat of the fruits, the old store; until the ninth year, until its fruits come in, ye shall eat the old store."

Despite some ambiguity here, it is clear enough that with fruits for three years specifically promised to be "commanded" by God for Israel, there would be sufficient for back-to-back sabbath years. There appears to be a perpetual extension of the principle inherent in the giving of the manna, wherein a double portion was given on the sixth day to provide for the sabbath (the seventh day) when none could be gathered.

"It shall bring forth produce for three years ..." (Leviticus 25:21). "What human being himself could have promised such a thing? Only God could make such a statement, and this makes it clear that none other but God Himself could have given Israel the Law on Mount Sinai."[13] Such a deduction is profoundly true, and it is likewise true in the instance of our Lord Jesus Christ's having promised his faithful followers, "There is no man that hath left house, or brethren, or sisters, or mother, or father, or children, or lands, for my sake and for the gospel's sake, but he shall receive a hundredfold now in this time, houses, and brethren, and sisters, and mothers and children, and lands, with persecutions, and in the world to come eternal life! (Mark 10:29-30). Only God Incarnate could have said such a thing!

"Ye shall do my statutes ..." The great factor in this whole institution was that God was the perpetual and sole Owner of the land (all of it), and that, just as the Canaanites had forfeited their right to it by their persistent wickedness, Israel too was never anything but "a tenant at will" (the will of God), so long as, but not any longer than, they were obedient to God's will. The tragic fact is evident that Israel never understood this at all, nor do those today who still imagine themselves to be the "Sons of Abraham" and insist upon their divine right to Palestine! An even greater tragedy is seen in the tacit acceptance of this falsehood by certain modern nations, including our own, who are leagued in treaties with Israel guaranteeing to that sinful nation an ownership to which they cannot possibly be legally entitled. Our own feeling is that unfolding history will yet rebuke and destroy that error.
