John Trapp on Isaiah 29:15

Ver. 15. Wo unto them that ſeek deep to hide] that carry two faces under a hood, as all Formaliſts and double-minded perſons do, deſirous to deceive the world, and if it were poſſible, God himſelf alſo, with their pretences and profeſſions, and to cozen him of heaven.

To hide their counſel] their cunning contrivances, ut ita liberè in omnes veneres & ſcelera ruant.

From the Lord] which cannot be, becauſe he is All-eye, and the ſearcher of hearts; he is intimo noſtro intimior nobis, and will bring to light the hidden things of darkneſs, 1 Cor. 4, 5.

Their works are in the dark] Out of ſight, but not out of the light of his countenance, Pſal. 90.8. Deo obſcura liquent, muta reſpondent, ſilentium confitetur, all things are naked and open before the eyes of him with whom we have to do, Heb. 4.13. Sin not therefore in hope of ſecrecy; Si non caſte tamen caute, will prove too ſhort a covering.

And ſay, who ſeeth us? and who knoweth us?] God doth, (to be ſure) whoever doth not, hold this faſt againſt that natural Atheiſm which is in us all; See Ezek. 9.9. Rom. 3.18. with the Note.
