Can anyone else see what an idiot this Ex-Christian was? A 4 way contradiction?

1, So an Ex-Christian bought a website to explain why he left the Bible that has so many contradictions, he was willing to spend money to save Christians from a book with many contradictions.

2, In the section of Ten Plagues, he found a 4 way contradiction. 3 against 4 against 6 (like a combination lock: 6 challenged 7 is 42 contradictions and 3 against 10 is 30 more,) so that is so many?

3, I list them by group, I can show NONE conflict, can anybody else?

4, Exodus 7,3 "I will harden Pharaoh’s heart"=10,1, total 2, ="the Lord hardened Pharaoh’s heart" 9,12, 10,20+27, 11,10 total 6.

5, "Pharaoh’s heart became hard" 7,13+22, 8,19 , 9,35 total 4.

6, "This time also Pharaoh hardened his heart" 8,32+15, 9,34 total 3.

Anybody else figure out none conflicted?
