Why is the bible full of stupid errors?

I wont call you an idiot. But judging from just the first part of your writing you didn't read the chapter or you are purposely trying too mislead people....And Joab gave up the sum of the number of the people unto the king: and there were in Israel eight hundred thousand valiant men that drew the sword; and the men of Judah were five hundred thousand men. This is1 Samuel which puts the total number at 1.3 okay 1.3 or 1.1 Is the number the important part of what God is trying to tell us? NO. he was telling us that David killed Goliath by faith in God. yet counted the numbers of his army and counted on his own strength and got defeated...God moving someone is not the same as telling them to do something, god did not want David to count the numbers of his army...that is clear by the fact it angered him....I could go through these one by one but alas i have run out of patience...if you got this information from someone else..then i would suggest you seek god for yourself...If you yourself came up with this perhaps you should spend more time searching for truth rather than looking for contradictions.
