What does the Bible say about the strength of Israel?

The term 'strength of Israel' is used in 1 Samuel 15:29 to refer to the Lord Jesus Christ. This title signifies His ability to save His people from their sins by bearing their guilt and fulfilling all righteousness on their behalf. In Isaiah 53, we see that He was wounded for our transgressions and bore our iniquities, showcasing the strength required for such an immense sacrifice. Without Him, we have no strength, which highlights our need for a Savior who can undertake what we cannot.
