Charles Ellicott Commentary Nehemiah 9:17

"and refused to obey, neither were mindful of thy wonders that thou didst among them, but hardened their neck, and in their rebellion appointed a captain to return to their bondage. But thou art a God ready to pardon, gracious and merciful, slow to anger, and abundant in lovingkindness, and forsookest them not." — Nehemiah 9:17 (ASV)

In their rebellion. —Rather, appointed a captain to return to their bondage in Egypt. This is the reading of some manuscripts, followed by the Septuagint, and is in harmony with Numbers 14:4, though there the appointment is only proposed.

A God ready to pardon. — A God of pardons; only in Daniel 9:9 and Psalm 130:4.
