Contradiction with Ecclesiastes 2:26
This verse states that God gives the sinner the task of gathering and collecting wealth that will eventually be given to the one who pleases God, which implies that one may not enjoy the fruits of their labor, contradicting the promise in Isaiah 62:9.
Ecclesiastes 2:26: For [God] giveth to a man that [is] good in his sight wisdom, and knowledge, and joy: but to the sinner he giveth travail, to gather and to heap up, that he may give to [him that is] good before God. This also [is] vanity and vexation of spirit. [in his...: Heb. before him]
Contradiction with Leviticus 26:16
This verse warns that God will set His face against people, resulting in sowing seed in vain as their enemies will eat it, which contradicts the assurance of enjoying the fruits of labor in Isaiah 62:9.
Leviticus 26:16: I also will do this unto you; I will even appoint over you terror, consumption, and the burning ague, that shall consume the eyes, and cause sorrow of heart: and ye shall sow your seed in vain, for your enemies shall eat it. [over: Heb. upon]
Contradiction with Haggai 1:6
This verse speaks about sowing much but bringing in little, which contradicts the assurance of enjoying the fruits of labor in Isaiah 62:9.
Haggai 1:6: Ye have sown much, and bring in little; ye eat, but ye have not enough; ye drink, but ye are not filled with drink; ye clothe you, but there is none warm; and he that earneth wages earneth wages [to put it] into a bag with holes. [with holes: Heb. pierced through]
Contradiction with Amos 5:11
This verse states that though one plants pleasant vineyards, they shall not drink the wine thereof, contradicting the promise of enjoying one's own harvest in Isaiah 62:9.
Amos 5:11: Forasmuch therefore as your treading [is] upon the poor, and ye take from him burdens of wheat: ye have built houses of hewn stone, but ye shall not dwell in them; ye have planted pleasant vineyards, but ye shall not drink wine of them. [pleasant...: Heb. vineyards of desire]
Contradiction with Micah 6:15
This verse states that people will sow but not reap, and tread olives but not anoint themselves with oil, which is contradictory to the assurance in Isaiah 62:9.
Micah 6:15: Thou shalt sow, but thou shalt not reap; thou shalt tread the olives, but thou shalt not anoint thee with oil; and sweet wine, but shalt not drink wine.
