Did Spurgeon read Walther?

Charles H. Spurgeon (1834-1892), in his Sunday sermon, December 31, 1871, preached from Nehemiah 8:10:
Holy sorrow is precious before God, and is no bar to godly joy. Let it be carefully noted...that abounding mourning is no reason why there should not speedily be seen an equally abundant joy, for the very people who were bidden by Nehemiah and Ezra to rejoice were even then melted with penitential grief, "for all the people wept when they heard the words of the law."
The vast congregation under the teaching of Ezra, were awakened and cut to the heart; they felt the edge of the law of God like a sword opening up their hearts, tearing, cutting, and killing, and well might they lament: then was the time to let them feel the gospel's balm and hear the gospel's music, and, therefore, the former sons of thunder changed their note, and became sons of consolation, saying to them, "This day is holy unto the Lord your God; mourn not, nor weep. Go your way eat the fat, and drink the sweet, and send portions unto them for whom nothing is prepared: for this day is holy unto our Lord: neither be ye sorry; for the joy of the Lord is your strength."
