2. Day unto day uttereth speech , and night unto night sheweth knowledge .

Or rather, after (as the Hebrew Lamed oft signifies, as Exod. 16. 1. and 29. 38. 2 Chron. 30. 21. Psal. 96. 2.) Day: For the day doth not utter this to the Day, but to us upon the Day. The Sence is, Either, 1. That orderly and constant, and useful Succession of Days and Nights one after another, declare this▪ But of the Course of the Sun, the effect whereof this Succession is, he speaks, v. 5. Or rather, 2. Every Day and Night renews or repeats these Documents and Demonstrations of God's Glory. He that neglects them one day, may learn them the next day.

Or, poureth forth, to wit, constantly and abundantly and forcibly, as a Fountain doth Waters, as this Hebrew Verb signifies.

Or the Word, or Discourse, To wit, Concerning God. It hath as it were a Tongue to speak the Praises of it's Maker; (i. e.) It gives men occasion to Magnifie and adore him.

(i. e.) Gives us a clear and certain Knowledge or Discovery of God their Authors.
