1 Chronicles 18:4

And David took from him a thousand chariots and seven thousand horsemen and twenty thousand footmen. The apparent discrepancy between this statement and that of 2 Samuel 8:4 is due to the fact that in the latter passage the Hebrew text is a trifle corrupt. David also houghed all the chariot horses, by hamstringing them, but reserved of them an hundred chariots, probably for a triumphal procession upon his return.
