Nehemiah 9:7
Thou art the LORD the God, who didst choose Abram, and broughtest him forth out of Ur of the Chaldees, and gavest him the name of Abraham; Thou art the LORD the God, who didst choose Abram, and broughtest him forth out of Ur of the Chaldees, and gavest him the name of Abraham;
After the reading of God's requirements in Nehemiah 8 had affected the people, Nehemiah 9 rehearses the Lord's works on behalf of His people, and this verse stands within that rehearsal. Choosing Abram, bringing him out of Ur of the Chaldees, and giving him the name Abraham is set forth as one of those acts for His people and as an instance of God's goodness in Israel's history. That goodness is placed alongside the people's ingratitude and turning from God, which separated them from God and led Him to permit heathen nations to control them, showing that He would not serve with their sins.
The verse belongs to a prayer in which Ezra and Nehemiah humbled themselves before God, confessed their own sins and the people's sins, and pleaded for pardon as though they themselves were the offenders. Remembering this history led the people to acknowledge the justice of their punishment. From that acknowledgment they went on to pledge obedience to God's law.
