I just read Morphew’s section on the beatitudes. He points out that Jesus’ “blessed are the meek for they shall inherit the earth” is very much a reference to PS 37. Rabbis would regularly quote a few words knowing their audience would know the entire passage.
Click through to the link above and read Psalm 37 in light of Jesus’ sermon. Wow! Meekness is not weakness. It’s trust. The meek trust God will bring to pass what He’s promised!
