Keluaran 6:8

6:8 I will bring you to the land I swore to give ¹  to Abraham, to Isaac, and to Jacob – and I will give it to you ²  as a possession. I am the Lord!’”

Keluaran 11:5

11:5 and all the firstborn in the land of Egypt will die, from the firstborn son of Pharaoh ³  who sits on his throne, to the firstborn son of the slave girl who is at her hand mill, and all the firstborn of the cattle.

[6:8]  ¹ tn Heb “which I raised my hand to give it.” The relative clause specifies which land is their goal. The bold anthropomorphism mentions part of an oath-taking ceremony to refer to the whole event and reminds the reader that God swore that he would give the land to them. The reference to taking an oath would have made the promise of God sure in the mind of the Israelite.

[6:8]  ² sn Here is the twofold aspect again clearly depicted: God swore the promise to the patriarchs, but he is about to give what he promised to this generation. This generation will know more about him as a result.

[11:5]  ³ sn The firstborn in Egyptian and Israelite cultures was significant, but the firstborn of Pharaoh was most important. Pharaoh was considered a god, the son of Re, the sun god, for the specific purpose of ruling over Re’s chief concern, the land of Egypt. For the purpose of re-creation, the supreme god assumed the form of the living king and gave seed which was to become the next king and the next “son of Re.” Moreover, the Pharaoh was the incarnation of the god Horus, a falcon god whose province was the heavens. Horus represented the living king who succeeded the dead king Osiris. Every living king was Horus, every dead king Osiris (see J. A. Wilson, “Egypt,” Before Philosophy, 83-84). To strike any firstborn was to destroy the heir, who embodied the hopes and aspirations of the Egyptians, but to strike the firstborn son of Pharaoh was to destroy this cardinal doctrine of the divine kingship of Egypt. Such a blow would be enough for Pharaoh, for then he would drive the Israelites out.
