Matthew Poole and continuators on Hebrews 3:10

10 Wherefore I was grieved with that generation , and said, They do alway err in their hearts , and they have not known my ways .

Because they thus tempted and proved him by hardning their hearts in unbelief▪ Forty Years, God the Redeemer, Isaiah 63.16. 1 Cor. 10.9. was grieved, is attributed to him improperly, who is not subject to Passions, but as Men grown impatient with grievous and oppressive Burdens; so He expresseth his dislike, disdain of them, and resolution to bear no longer, as Amos 2.13. They split on him, as a Ship on a sharp point of a Rock, so as God hath loss, offence and trouble by it; and all of them did so carry it to Him the whole Age of them but Caleb and Ioshua, Psal. 95.10.

They follow Deceit and Lying in their Doctrine and Worship with all their Heart, so that it is diffused through their Persons, and that seat of Truth is made depth of Error, to the stupifying of their Hearts even to very madness, and this was their state all their time.

Notwithstanding God's Works were among them and his Word, yet they would not know his Mind, so as to approve, love, and walk in God's ways. His Law, Doctrine, revealed Truth and Commands were all cast behind their Back, Ezek. 23.35.
