The Lord hath taken you Of his own free mercy, unmerited by you; and brought you forth out of the iron furnace The furnace wherein iron and other metals are melted, to which Egypt is compared, from the torment and misery which the Israelites there endured. To be unto him a people of inheritance His peculiar possession from generation to generation; and therefore for you to forsake God, and worship idols, would be wickedness and ingratitude to the highest degree.
