Isaac was the son of promise to Abraham and Sarah, and the half-brother of Ishmael (who became the father of the Arab people) and the father of Esau (from whom came the Edomites) and Jacob. Isaac was born of a mother beyond childbearing age by a miracle of Yahweh, and was a focus of the testing of Abraham and Sarah, his parents.
The name Isaac means "to laugh, or he laughs," which is based on the response of Sarah to Yahweh's statement to Abraham that she was to bear a son. Sarah was hiding out of sight when this announcement was made by the Angel of Yahweh, and upon hearing this statement, she laughed, which she denied later before the angel. Such an idea was considered impossible but happened as promised by the heavenly visitor. Later, Abraham's faith was tested when God commanded him to sacrifice his only son, Isaac. He followed through with this command of God but received him back alive, since Yahweh kept him from doing so, declaring that now He knew by experience (see the meaning of Hebrew yada') that Abraham did not withhold his son.
Later in Isaac's life, he married Rebekah, who bore him Jacob (biography) and Esau (his favorite), and was tricked by Jacob and Rebekah into giving his younger son Jacob his blessing.
Isaac was one of the sons of Abraham and Sarah, and brother of Ishmael. He was born to Abraham and Sarah, when she was beyond childbearing age, by the miracle of God. God instructed Abraham to sacrifice his son on Mt. Moriah, as a means to test the faith of Abraham. At the last moment before this sacrifice, God stopped Abraham from doing this, demonstrating His commitment to God. Isaac married Rebekah, through whom were born Esau and Jacob, the latter deceiving his father Isaac to receive the blessing of the firstborn, causing considerable animosity from Esau.
1These are the words of the covenant which Yahweh commanded Moses to make with the children of Israel in the land of Moab, in addition to the covenant which he made with them in Horeb. 2Moses called to all Israel, and said to them:
Your eyes have seen all that Yahweh did in the land of Egypt to Pharaoh, and to all his servants, and to all his land; 3the great trials which your eyes saw, the signs, and those great wonders. 4But Yahweh has not given you a heart to know, eyes to see, and ears to hear, to this day. 5I have led you forty years in the wilderness. Your clothes have not grown old on you, and your sandals have not grown old on your feet. 6You have not eaten bread, neither have you drunk wine or strong drink, that you may know that I am Yahweh your God. 7When you came to this place, Sihon the king of Heshbon and Og the king of Bashan came out against us to battle, and we struck them. 8We took their land, and gave it for an inheritance to the Reubenites, and to the Gadites, and to the half-tribe of the Manassites. 9Therefore keep the words of this covenant and do them, that you may prosper in all that you do. 10All of you stand today in the presence of Yahweh your God: your heads, your tribes, your elders, and your officers, even all the men of Israel, 11your little ones, your wives, and the foreigners who are in the middle of your camps, from the one who cuts your wood to the one who draws your water, 12that you may enter into the covenant of Yahweh your God, and into his oath, which Yahweh your God makes with you today, 13that he may establish you today as his people, and that he may be your God, as he spoke to you and as he swore to your fathers, to Abraham, to Isaac, and to Jacob. 14Neither do I make this covenant and this oath with you only, 15but with those who stand here with us today before Yahweh our God, and also with those who are not here with us today 16(for you know how we lived in the land of Egypt, and how we came through the middle of the nations through which you passed; 17and you have seen their abominations and their idols of wood, stone, silver, and gold, which were among them); 18lest there should be among you man, woman, family, or tribe whose heart turns away today from Yahweh our God, to go to serve the gods of those nations; lest there should be among you a root that produces bitter poison; 19and it happen, when he hears the words of this curse, that he bless himself in his heart, saying, “I shall have peace, though I walk in the stubbornness of my heart,” to destroy the moist with the dry. 20Yahweh will not pardon him, but then Yahweh’s anger and his jealousy will smoke against that man, and all the curse that is written in this book will fall on him, and Yahweh will blot out his name from under the sky. 21Yahweh will set him apart for evil out of all the tribes of Israel, according to all the curses of the covenant written in this book of the law.
22The generation to come—your children who will rise up after you, and the foreigner who will come from a far land—will say, when they see the plagues of that land, and the sicknesses with which Yahweh has made it sick, 23that all of its land is sulfur, salt, and burning, that it is not sown, doesn’t produce, nor does any grass grow in it, like the overthrow of Sodom, Gomorrah, Admah, and Zeboiim, which Yahweh overthrew in his anger, and in his wrath. 24Even all the nations will say, “Why has Yahweh done this to this land? What does the heat of this great anger mean?”
25Then men will say, “Because they abandoned the covenant of Yahweh, the God of their fathers, which he made with them when he brought them out of the land of Egypt, 26and went and served other gods and worshiped them, gods that they didn’t know and that he had not given to them. 27Therefore Yahweh’s anger burned against this land, to bring on it all the curses that are written in this book. 28Yahweh rooted them out of their land in anger, in wrath, and in great indignation, and thrust them into another land, as it is today.”
29The secret things belong to Yahweh our God; but the things that are revealed belong to us and to our children forever, that we may do all the words of this law.
