Contradiction with Exodus 32:14
This verse describes God repenting of the evil He thought to do unto His people, suggesting a change in God's intentions, whereas Exodus 30:11 suggests a direct and unchanging command from God.
Exodus 32:14: And the LORD repented of the evil which he thought to do unto his people.
Contradiction with Numbers 23:19
This verse states that God is not a man, that He should lie; neither the son of man, that He should repent, which contradicts the idea of God changing directives as seen in Exodus 30:11.
Numbers 23:19: God [is] not a man, that he should lie; neither the son of man, that he should repent: hath he said, and shall he not do [it]? or hath he spoken, and shall he not make it good?
Contradiction with Malachi 3:6
This verse emphasizes that God does not change, which seems contrary to the notion of providing specific conditional instructions in Exodus 30:11.
Malachi 3:6: For I [am] the LORD, I change not; therefore ye sons of Jacob are not consumed.
