New Defender's Study Bible Notes
118:22 head stone. Although much in this key psalm may well be appropriated by each believer, it primarily is fulfilled in Christ, as shown by the use of this verse in the New Testament (e.g., Matthew 21:42; Acts 4:11; I Peter 2:7). According to Jewish tradition, the stones for Solomon’s temple, quarried and shaped far from the temple site, included one odd-shaped stone which did not fit anywhere. It was finally found to be the main cornerstone (possibly capstone) of the entire structure.
