PSALMS 105:8-10 niv 8 He remembers his covenant forever, the promise he made, for a thousand generations, 9 the covenant he made with Abraham, the oath he swore to Isaac. 10 He confirmed it to Jacob as a decree, to Israel as an everlasting covenant:
Been trying to find out were God had sworn to Isaac but could only find the oath given to Abraham
Genesis 22:15 NIV
15 The angel of the Lord called to Abraham from heaven a second time 16 and said, “I swear by myself, declares the Lord, that because you have done this and have not withheld your son, your only son,
Genesis 24:6-7 NIV
6 “Make sure that you do not take my son back there,” Abraham said. 7 “The Lord, the God of heaven, who brought me out of my father’s household and my native land and who spoke to me and promised me on oath, saying, ‘To your offspring[a] I will give this land’—he will send his angel before you so that you can get a wife for my son from there.
This is further reiterated in the book of Hebrews
Hebrews6:13 NIV
13 When God made his promise to Abraham, since there was no one greater for him to swear by, he swore by himself, 14 saying, “I will surely bless you and give you many descendants.”[d] 15 And so after waiting patiently, Abraham received what was promised.
