How long was the period from Abraham to Christ's first advent?

The period from Abraham to Christ's first advent was approximately 2,000 years, described as round figures. This era was part of a broader timeline that included 2,000 years to Abraham, during which God dealt primarily with the favored nation of Israel, with some exceptions.

Les explains on the chart that there were 2,000 years to Abraham, and then from Abraham until Christ's first advent, another 2,000 years, round figures. During that period, God dealt only with this favored nation, with some exceptions, primarily with the nation of Israel. Even after the crucifixion, in the early chapters of Acts, Peter addressed the children of Israel and pleaded with them to respond to the fact that the one they crucified was their Messiah, but Israel nationally would not believe it.
