Contradiction with Isaiah 1:15
This verse suggests that God does not always listen to prayers, especially when hands are full of blood, contradicting the idea that God immediately responded to Moses in Exodus 8:30.
Isaiah 1:15: And when ye spread forth your hands, I will hide mine eyes from you: yea, when ye make many prayers, I will not hear: your hands are full of blood. [make...: Heb. multiply prayer] [blood: Heb. bloods]
Contradiction with Proverbs 28:9
Whoever turns away their ear from hearing the law, even their prayer shall be an abomination, which contrasts with Exodus 8:30, where a prayer is answered positively without mention of adherence to the law.
Proverbs 28:9: He that turneth away his ear from hearing the law, even his prayer [shall be] abomination.
Contradiction with Lamentations 3:44
States that God may cover Himself with a cloud so that prayer cannot pass through, which contradicts the immediate and visible response found in Exodus 8:30.
Lamentations 3:44: Thou hast covered thyself with a cloud, that [our] prayer should not pass through.
Contradiction with James 4:3
When asking, you do not receive because you ask with wrong motives, contrary to the success of Moses' intercession without questioning his motives in Exodus 8:30.
James 4:3: Ye ask, and receive not, because ye ask amiss, that ye may consume [it] upon your lusts. [lusts: or, pleasures]
Contradiction with 1 Peter 3:12
This verse says the Lord's ears are open unto the righteous, suggesting conditional listening which contrasts the straightforward response to Moses in Exodus 8:30.
1 Peter 3:12: For the eyes of the Lord [are] over the righteous, and his ears [are open] unto their prayers: but the face of the Lord [is] against them that do evil. [against: Gr. upon]
