John Trapp on Nehemiah 9:19

Verſe 19. Yet thou in thy manifold mercies] Nothing elſe could have kept him from turning them off, and ſaying to them as once Jephta did, Judg. 11. Behold ye have thruſt me out: and do ye come unto me in your diſtreſſe? Go, cry unto the Gods which ye have choſen: Let them deliver you in the time of your Tribulation, Judg. 10.

Forſookeſt them not in the Wilderneſſe] And yet he was neare the matter, when he would own them no longer, but even fathered them upon Moſes, ſaying, Exod. 32.7. Thy people which thou broughteſt out of the Land of Egypt, have corrupted themſelves.

The pillar of cloud departed not] It is ſad with a people when God ſends for his Love-tokens (his Ordinances) when they have ſinned away their light; and ſo wiped off all their comfortables.
