Psalm 144 Mar. 20 By David.  1Blessed be Yahweh, my rock, who teaches my hands to war, and my fingers to battle: 2my source of grace, my fortress, my high tower, my deliverer, my shield and He in whom I take refuge; who subdues my people under me. 3Yahweh, what is man, that You care for him? Or the son of man, that You think of him? 4Man is like a breath, his days are like a shadow that passes away. 5Part Your heavens, Yahweh, and come down; touch the mountains, and they will smoke. 6Throw out lightning and scatter them. Send out Your arrows and defeat them. 7Stretch out Your hand from above, rescue me and deliver me out of great waters, out of the hands of foreigners; 8whose mouths speak deceit, whose right hand is a right hand of falsehood. 9I will sing a new song to You, God, on a ten-stringed lyre I will sing praises to You. 10You are He who gives salvation to kings, who rescues David His servant from the deadly sword. 11Rescue me, and deliver me out of the hands of foreigners, whose mouths speak deceit, whose right hand is a right hand of falsehood.  12Then our sons will be like well-nurtured plants, our daughters like corner stones carved to adorn a palace. 13Our barns will be full, filled with all kinds of provision; our sheep will bring forth thousands and ten thousands in our fields. 14Our oxen will pull heavy loads, there will be no breaking in and no going away, and no crying in our streets. 15Happy are the people who are in such a situation. Happy are the people whose God is Yahweh.   

Commentary

144:1,2 My rock... my fortress, my high tower- There are references in the historical record to how David took refuge from Saul (:3) and other enemies in these things (1 Sam. 23:29; 2 Sam. 5:7,9). But David saw that the essence of his safety was not in them but in God. We may use medicines, doctors, insurance, emergency phone numbers... but the essence is that God is our saviour, even if He works through those things.
144:12 David must have shocked many by singing of how our sons shall be as plants and our daughters as corner stones. For the corner stones of a family were perceived to be the male head of the family. The Biblical view of women always sharply contrasted with that of the surrounding world at the time; such is God’s valuing of each of His children regardless of their gender or perception within society.
