How many years between the birth of Jesus and Isaiah?

It is impossible to know the exact amount of years. However, Jesus was born in the year 0AD, because the previous years all ended in BC, which meant Before Christ). Jesus' birth is the beginning of the New Testament, whereas Abraham lived very early on in the Old Testament, and so there would have been several hundred, if not thousands, of years between them.

About 2021 years, give or take a few, passed between Abraham's birth and Jesus' birth. BC 537 is when the captivity ended, plus seventy years of captivity is 607. 390 years passed between the captivity and Solomon's reign, and solomon reigned for 40 years, making 1037 BC. Solomon's reign began in the 480th year after Israel made it back to Canaan from Egypt. Israel were in captivity for 400 years, and they wandered in the desert for 30. 430+479=909, and 909+1037=1946 BC. Abraham was 75 at the time. 1946 BC plus 75 is 2021 BC, when Abraham was born.
