Psalms 8:1-9, “1 O יהוה, our Master, how excellent is Your Name in all the earth, You who set Your splendour above the heavens! 2 Out of the mouth of babes and infants You have founded strength, Because of Your adversaries, To put an end to enemy and avenger. 3 For I see Your heavens, the work of Your fingers, The moon and the stars, which You have established. 4 What is man that You remember him? And the son of man that You visit him? 5 Yet You have made him a little less than the Mighty One, and have crowned him with esteem and splendor. 6 You made him rule over the works of Your hands; You have put all under his feet, 7 All sheep and oxen, And also the beasts of the field, 8 The birds of the heavens, And the fish of the sea, Passing through the paths of the seas. 9 O יהוה, our Master, How excellent is Your Name in all the earth!”
