Isaac

Isaac was the long-promised son born to Abraham and Sarah in their old age, as recorded in Genesis. He was the child of the covenant, through whom God had promised to fulfill his purposes for Abraham's descendants (Genesis 17:19,21). Isaac was circumcised on the eighth day (Genesis 21:4) and grew up as Abraham's heir. When he was a youth, God tested Abraham by commanding him to offer Isaac as a sacrifice (Gen.22). Abraham obeyed, but at the last moment God provided a ram as a substitute. This event foreshadowed God's provision of his own Son as the ultimate sacrifice. Isaac married Rebekah, and they had twin sons, Esau and Israel (or 'Jacob') (Genesis 25:21-26). Isaac favored Esau, while Rebekah favored Jacob, leading to family conflict. Jacob deceived Isaac into giving him the firstborn blessing (Gen.27). Isaac settled in Gerar, where God confirmed to him the covenant promises (Genesis 26:1-5). Like his father, he passed off his wife as his sister out of fear (Genesis 26:7-11). He reopened Abraham's wells and dug new ones, showing his claim to the land. Isaac died at the age of 180 and was buried by his sons (Genesis 35:29). God is identified as the God of Abraham, Isaac and Jacob, linking Isaac to the patriarchal promises (Exodus 3:6). The New Testament upholds Isaac as an example of faith (Hebrews 11:20) and miraculous birth (Galatians 4:28-29).
