John 5:47

⁴⁵ Do not think that I will accuse you before the Father. Your accuser is Moses, in whom you have put your hope.

⁴⁶ If you had believed Moses, you would believe Me, because he wrote about Me.

But since you do not believe what he wrote, how will you believe what I say?”

Do read the surrounding verses too, because the context often says more than a single verse.
