Why God Waited Twenty Generations to Find Abraham

Twenty Generations of Silence

The genealogies in Genesis read like a list of missed opportunities. Adam begat Seth. Seth begat Enosh. Generation after generation, names and lifespans, and in almost all of them, nothing. No divine conversation. No call to go somewhere. No covenant. God created the world and then, by the measure of the Torah, spent ten generations barely speaking to it.

Then came Noah, and God spoke again. And after Noah, another ten generations of near-silence until Abraham. Rabbi Azarya, in Bereshit Rabbah, the Palestinian midrash on Genesis compiled in the 5th century CE, looked at this pattern and asked the obvious question: God's patience across all those generations was not indifference. It was something more intentional than that.

What Righteousness Means When No One Is Watching

The verse Rabbi Azarya quoted was from Psalms: you love righteousness and hate wickedness, therefore God has anointed you above your companions. The Psalm was not about Abraham. Rabbi Azarya applied it to Abraham anyway, because the structure it described matched his case exactly.

God did not love righteousness in the abstract. God loved the person who chose righteousness in the particular conditions of his own life. Abraham had been born into a world of idols, into a family that made them, in a culture that organized itself entirely around their worship. His father Terah ran a shop selling idols. Abraham had grown up behind the counter. When he began to see through the system, there was no tradition to support him, no community of skeptics, no accumulated argument he could borrow. He reasoned himself to monotheism alone.

The Double Command

When God finally spoke to Abraham, the command came in an unusual form. Lekh lekha. Go forth. The phrase doubled back on itself, it literally meant something like go to yourself, go for yourself, go from yourself. Rabbi Yehuda in Bereshit Rabbah read it as promise: this journey will be for your benefit and your good. Rabbi Nehemya read it differently: it was calling Abraham toward himself, toward the self that existed beneath the accumulated layers of where he had come from.

Both readings assumed that the command to leave was inseparable from the question of who Abraham actually was. God was not simply moving a useful person to a useful location. God was asking Abraham to become, through the act of departure, more fully what he already was in potential.

What Philo Saw in the Covenant

The Alexandrian Jewish philosopher Philo, writing in the first century CE in Greek, read the covenant between Abraham and God through a different lens. The covenant, in Philo's reading, was not primarily about land or descendants. It was about the quality of the person with whom God was making an agreement. God was not looking for perfection. Perfection was an impossible standard for any creature bound to a material body. God was looking for someone whose direction was consistently upward, whose failures were overcome by genuine effort.

Abraham's failures were real. He lied about Sarah twice. He complied with Sarah's demand to send Hagar and Ishmael away. He was not a figure of consistent virtue in the narrative. What he was, in Philo's reading and in the rabbinic reading both, was a figure who moved toward God even when the movement was imperfect.

Why He Stopped at Ten

In the famous negotiation over Sodom, Abraham bargained God down from fifty righteous people to ten. At ten he stopped. The tradition asked why. He did not stop because he ran out of nerve. He stopped because he calculated that ten was the minimum necessary for a community to constitute itself as a moral unit, and below that number, there was no community to save. He stopped not from cowardice but from precision.

The rabbis found in this stopping the same quality they found in all of Abraham. He was not performing righteousness for an audience. He was reasoning toward what was actually correct and then acting on his reasoning, even when the action was to stop bargaining for a city's survival.
