A:The Bible tells us nothing about the childhood of Abraham, simply saying (Genesis 11:26,27) that Terah begat Abram (Abraham), then (Genesis 11:29) that Abram took a wife. It appears later in Genesis that Sarai (later: Sarah) was also Abraham's sister. Bruce Feiler (Abraham) says that probably less than one per cent of the stories told about Abraham appear in The Bible. The vast majority did not even come into circulation until hundreds, even thousands of years after he would have lived. This includes the midrash in which Abraham, as a boy, is supposed to have proven to his father that his idols were powerless.
