Contradiction with Exodus 32:4
Nehemiah 9:18 highlights the sin of making a golden calf, while Exodus 32:4 describes how Aaron presented the calf as gods that led Israel out of Egypt.
Exodus 32:4: And he received [them] at their hand, and fashioned it with a graving tool, after he had made it a molten calf: and they said, These [be] thy gods, O Israel, which brought thee up out of the land of Egypt.
Contradiction with Deuteronomy 9:16
Nehemiah 9:18 emphasizes the people's idolatry, whereas Deuteronomy 9:16 states that Moses saw the calf and the people's corrupt actions upon descending the mountain.
Deuteronomy 9:16: And I looked, and, behold, ye had sinned against the LORD your God, [and] had made you a molten calf: ye had turned aside quickly out of the way which the LORD had commanded you.
Contradiction with Psalms 106:19-20
Nehemiah 9:18 condemns idol worship, but Psalms 106:19-20 recounts how the Israelites exchanged their glory for the image of an ox.
Psalms 106:19-20: They made a calf in Horeb, and worshipped the molten image.
Paradox #1
The conflict with Nehemiah 9:18 is that it involves the Israelites creating a golden calf to worship, contradicting their belief in worshiping only one God. Despite knowing they shouldn't make idols, they do so anyway, showing inconsistency in their actions and beliefs.
