What were the practices of the early Hebrews?

Answer 1

According to Jewish tradition, the Hebrews believed in One God from the time of Abraham onward. They kept the ways of Abraham on a voluntary basis until the Giving of the Torah in the time of Moses, which made it obligatory.

Brief glimpses at the traditions of Abraham are given in Genesis (ch.12-25); but since his teachings were later subsumed into the Torah in general, the Torah itself provides the best picture of the ways of the early Hebrews, with its laws of kindness, social justice, honesty in business, marital rights for women, etc.
