Blessed is the people of whom this is true; blessed is the people whose God is the Lord

Psalm 144:1-15

Praise the Lord. He is my loving God and my fortress, my stronghold and my deliverer, my shield, in whom I take refuge, who subdues peoples under me.

Lord, what are human beings that you care for them, mere mortals that you think of them? They are like a breath; their days are like a fleeting shadow.

Reach down your hand from on high; deliver me and rescue me from the mighty waters, from the hands of foreigners whose mouths are full of lies, whose right hands are deceitful.

I will sing a new song to you, my God; on the ten-stringed lyre I will make music to you, to the One who gives victory to kings, who delivers his servant David.

Then our sons in their youth will be like well-nurtured plants, and our daughters will be like pillars carved to adorn a palace. Our barns will be filled with every kind of provision. Our sheep will increase by thousands, by tens of thousands in our fields;  our oxen will draw heavy loads. There will be no breaching of walls, no going into captivity, no cry of distress in our streets. Blessed is the people of whom this is true; blessed is the people whose God is the Lord.
