In the King James Version of the Bible, it is mentioned in Num. 23:19 that God is not a human:
19 God is not a man, that he should lie; neither the son of man, that he should repent: hath he said, and shall he not do it? or hath he spoken, and shall he not make it good? KJV, 1769
Now we know that Jesus was a man, being the son of Mary. So, based on Num. 23:19, how can he also be God? I am requesting a Catholic perspective.
