Seems odd that it isn't on line. Its successor with the Pilgrims, the Bay Psalm Book, Cambridge, Mass., Stephen Day 1640 ("Whole Booke of Psalmes...," first book printed and entirely written in the Colonies) is in e-text here: Bay Psalm
It gives this for Psalm 100 (Book 4):

A psalm of praise

1 Make ye a joyful sounding noise
unto Jehovah, all the earh:
2 Serve ye Jehovah with gladness:
before his presence come with mirth.

3 Know that Jehovah he is God,
who hath us formed it is he,
and not ourselves: his own people
and sheep of his pasture are we.

4 Enter into his gates with praise,
into His courts with thankfulness:
make ye confession unto him,
and his name reverently bless.

5 Because Jehovah he is good,
for evermore is his mercy:
and unto generations all
continue doth his verity.

Note 'mirth,' not fear, in this text.
