Final answer:
God told Abraham that his descendants would be as numerous as the stars in the sky, which is part of the Covenant in Jewish belief and history.
Step-by-step explanation:
God told Abram, later known as Abraham, that his descendants would be as numerous as the stars in the sky. This promise is a fundamental aspect of the Covenant, a vital agreement in the Hebrew religion between God and Abraham. According to Jewish belief, the Covenant involves worship and devotion from the Hebrews, which in turn grants them numerous descendants, a prosperous land, and a special relationship with God. This biblical narrative illustrates the importance of Abraham as the first patriarch of the Hebrews and his role in Jewish history.
