Charles H. Spurgeon on Psalms 144:12

That our daughters may be as corner stones, polished after the similitude of a palace or temple. By daughters families are united and connected to their mutual strength, as the parts of a building are by the cornerstones; and when they are graceful and beautiful both in body and mind, they are then polished after the similitude of a nice and curious structure. When we see our daughters well established, and stayed with wisdom and discretion, as cornerstones are fastened in the building; when we see them by faith united to Christ, as the chief cornerstone, adorned with the graces of God's Spirit, which are the polishing of that which is naturally rough, and "become women professing godliness"; when we see them purified and consecrated to God as living temples, we think ourselves happy in them. —Matthew Henry.
