I was glad when they said unto me, Let us go into the house of the L.

-Bible (Old Testament)
ORDPsalms122:1.

   Since there's no help, come let us kiss and part; Nay, I have done, you get no more of me, And I am glad, yea glad with all my heart That thus so cleanly I myself can free; Shake hands forever, cancel all our vows, And when we meet at any time again, Be it not seen in either of our brows That we one jot of former love retain.

-Drayton, Michael
  Idea, sonnet 61.

But set down This, set down This: were we led all that way for Birth or Death? There was a Birth, certainly, We had evidence and no doubt. I had seen birth and death But had thought they were different; this Birth was Hard and bitter agony for us, like Death, our death. We returned to our places, these Kingdoms, But no longer at ease here, in the old dispensation, With an alien people clutching their gods. I should be glad of another death.

One morning, as I was sitting by the fire, a great cloud came over me, and a temptation beset me, and I sate still† And as I sate still under it and let it alone, a living hope rose in me, and a true voice arose in me which cried:There is a living God who made all things. And immediately the cloud and temptation vanished away, and the life rose over it all, and my heart was glad, and I praised the living God.

Lieutenant, is that your sword, or are you just glad to see me?

When you are old and greyand full of sleep, And nodding by the fire, take down this book, And slowly read, and dream of the soft look Your eyes had once, and of their shadows deep; How many loved your moments of glad grace, And loved your beauty with love false or true, But one man loved the pilgrim soul in you, And loved the sorrows of your changing face; And bending down beside the glowing bars, Murmur, a little sadly how Love fled And paced among the mountains overhead And hid his face amid a crowd of stars.
