The words are taken from the poem of The same name by Thomas Dekker (1572 - 1632). They are almost verbatim, but modernised a bit. This is the poem by Dekker.
Golden slumbers kiss your eyes,
Smiles awake you when you rise ;
Sleep, pretty wantons, do not cry,
And I will sing a lullaby,
Rock them, rock them, lullaby.
Care is heavy, therefore sleep you,
You are care, and care must keep you ;
Sleep, pretty wantons, do not cry,
And I will sing a lullaby,
Rock them, rock them, lullaby.
