Contradiction with Isaiah 51:10
Isaiah speaks of God making a way through the sea, aligning with the miraculous nature of Psalms 136:13, rather than contradicting it.
Isaiah 51:10: [Art] thou not it which hath dried the sea, the waters of the great deep; that hath made the depths of the sea a way for the ransomed to pass over?
Contradiction with Exodus 14:21
This verse describes the parting of the Red Sea, consistent with the act mentioned in Psalms 136:13, rather than contradicting it.
Exodus 14:21: And Moses stretched out his hand over the sea; and the LORD caused the sea to go [back] by a strong east wind all that night, and made the sea dry [land], and the waters were divided.
Paradox #1
The verse refers to the parting of the Red Sea, a miraculous event. The scientific conflict here is that there is no empirical evidence or natural explanation for such an event happening as described, where a sea would part to form dry land allowing for a large group of people to cross. Natural laws as we understand them don't account for seas splitting in such a manner without an evident cause.
