English Standard Version (ESV)
The phrase "By myself I have sworn" is significant because God, who can't swear by anything greater, uses His own being as the basis for His oath. This isn't just a declaration; it's God making an unbreakable commitment rooted in His own divine nature, assuring Abraham of the immutability of His promises.

English Standard Version (ESV)
After God tested Abraham by commanding him to sacrifice Isaac, the angel of the Lord intervenes at the last moment, preventing the act. In this exchange, the angel, speaking as the Lord Himself, solemnly swears by His own name, emphasizing the profound significance of Abraham's willingness to obey. This incredible demonstration of faith secures Abraham and his descendants an everlasting covenant and abundant blessings.
Why would an all-powerful God need to swear an oath? What does it mean when God swears 'by myself'?
In Genesis 22:16, God declares, 'By myself I have sworn.' This isn't because God needs to convince anyone, but rather to deeply reassure Abraham. Since God is perfect and true, He can only swear by His own perfect being. This is a profound declaration of His immutability and faithfulness. An oath is meant to settle matters and provide absolute certainty. When God swears by Himself, He is providing the ultimate guarantee for His promises, a guarantee rooted in His own unchanging nature.
This is why the New Testament speaks of God's oath concerning Abraham as a way to offer 'strong consolation' to believers (Hebrews 6:13-18). It's not just a word, but a divine pledge secured by His own eternal character, assuring us of the immutability of His counsel and promises.
Who is speaking in this passage? Is it an angel, or God Himself?
The text presents a fascinating interaction. The 'angel of the LORD' calls out to Abraham (Genesis 22:11), stopping him from sacrificing Isaac. Then, immediately after, the text states, 'And said, By myself I have sworn, saith the LORD.' This transition from 'angel of the LORD' to 'LORD' (Jehovah) speaking in the first person is significant. It reveals that the Angel speaking is not merely a messenger, but is God Himself.
This is not the only instance where the 'angel of the LORD' speaks and acts with divine authority, sometimes even identifying Himself as God. It points to a pre-incarnate appearance of Jesus Christ, the Son of God, acting as the representative of the LORD in human history, empowered to make divine declarations and covenants.

Why an oath, after so many promises? What does this oath confirm for Abraham?
Abraham had already received numerous promises from God regarding his descendants and their future (Genesis 12, 15, 17). Yet, after the ultimate test of faith – nearly sacrificing Isaac – God ratifies these promises with a solemn oath.
This oath in Genesis 22:16-18 isn't just a repetition of past promises; it's a profound confirmation and expansion. God swears 'by myself,' signifying the unbreakable nature of this covenant. The promises now assure Abraham of:
This divine oath solidifies Abraham's faith and provides assurance, not just for him, but for all who would later believe and be counted as his spiritual offspring. It underscores that God's covenant is built on His faithful character, not solely on human performance, even when that performance is heroic obedience.
