New Defender's Study Bible Notes
1:5 ye will not believe. Compare this verse to Isaiah 53:1, which similarly marvels at the inexcusable unbelief of the children of Israel at the great work of God. This unbelief will be especially manifest when they are dispersed “among the heathen.” The work of God which they reject is nothing less than the sending of His own Son to die for their sins, then rise again. See Acts 13:41.
