Contradiction with Ecclesiastes 9:11
While 1 Chronicles 24:12 is partly about organized priestly duties, Ecclesiastes 9:11 emphasizes the unpredictability of life and events, suggesting not everything is orderly or determined.
Ecclesiastes 9:11: I returned, and saw under the sun, that the race [is] not to the swift, nor the battle to the strong, neither yet bread to the wise, nor yet riches to men of understanding, nor yet favour to men of skill; but time and chance happeneth to them all.
Contradiction with Matthew 23:23
1 Chronicles 24:12 focuses on the priestly service and division, whereas Matthew 23:23 criticizes religious leaders for their focus on meticulous law observance rather than justice, mercy, and faith.
Matthew 23:23: Woe unto you, scribes and Pharisees, hypocrites! for ye pay tithe of mint and anise and cummin, and have omitted the weightier [matters] of the law, judgment, mercy, and faith: these ought ye to have done, and not to leave the other undone. [anise: Gr. dill]
Contradiction with Hebrews 7:11-12
1 Chronicles 24:12 deals with the established order of priestly divisions, but Hebrews 7:11-12 suggests a change in priesthood and law with the coming of Christ, indicating a shift from established tradition.
Hebrews 7:11-12: If therefore perfection were by the Levitical priesthood, (for under it the people received the law,) what further need [was there] that another priest should rise after the order of Melchisedec, and not be called after the order of Aaron?
