Psalm 130 (131), as for Evening Prayer for Tuesday of week 3

 [Benedictine Daily Prayer: A Short Breviary has the very nearly the
  version I like best, but what follows is the Dominican antiphon]

 Learn from me, says the Lord, I am gentle and lowly of heart,
  you will find rest for your souls

 Oh Lord my heart is not proud, nor haughty my eyes
 I have not gone after things too great, nor marvels beyond me
 Truly I have set my soul, in silence and peace
 Like a weaned child in its mother's arms, even so is my soul
 Oh Israel hope in the Lord, both now and for ever

 Learn from me, says the Lord, I am gentle and lowly of heart,
  you will find rest for your souls
