A.T. Robertson Commentary Matthew 19:29

"And every one that hath left houses, or brethren, or sisters, or father, or mother, or children, or lands, for my name`s sake, shall receive a hundredfold, and shall inherit eternal life." — Matthew 19:29 (ASV)

A hundredfold (εκατονπλασιονα). But Westcott and Hort read πολλαπλασιονα, manifold. Eternal life is the real reward.
