From Lorraine Inserra and H. Wiley Hitchcock, The Music of Henry Ainsworth's Psalter (Amsterdam, 1612) (I.S.A.M. Monographs: Number 15, 1981, pp. 114-15):

Psalm 100

Showt to Jehovah al the earth.
   Serv ye Jehovah with gladnes;
before him come with singing merth.
   Know that Jehovah he God is.

It's he that made us and not were,
   his folk and sheep of his feeding.
O with confession enter yee
   his gates, his courtyards with praising.

Confess to him; bless ye his name,
   because Jehovah he good is.
His mercy ever is the same,
   and his faith unto al ages.
