Newton said light would be deflected by mass????

Nobody suggested that Newton made this prediction. It was others who followed who used his theory.

Henry Cavendish, Johann von Soldner, and the deflection of light, Clifford M. Will, Am. J. Phys. 56, 413 (1988)

The gravitational deflection of light based on Newtonian theory and the corpuscular model of light was calculated, but never published, around 1784 by Henry Cavendish, almost 20 years earlier than the first published calculation by Johann Georg von Soldner. The two results are slightly different because, while Cavendish treated a light ray emitted from infinity, von Soldner treated a light ray emitted from the surface of the gravitating body. At the first order of approximation, they agree with each other; both are one-half the value predicted by general relativity and confirmed by experiment.
