15 So on October 2 the wall was finished-just fifty-two days after we had begun. 16 When our enemies and the surrounding nations heard about it, they were frightened and humiliated. They realized this work had been done with the help of our God. 17 During those fifty-two days, many letters went back and forth between Tobiah and the nobles of Judah. 18 For many in Judah had sworn allegiance to him because his father-in-law was Shecaniah son of Arah, and his son Jehohanan was married to the daughter of Meshullam son of Berekiah. 19 They kept telling me about Tobiah's good deeds, and then they told him everything I said. And Tobiah kept sending threatening letters to intimidate me.

Commentary on Nehemiah 6:15-19

(Read Nehemiah 6:15-19)

The wall was begun and finished in fifty-two days, though they rested on the sabbaths. A great deal of work may be done in a little time, if we set about it in earnest, and keep close to it. See the mischief of marrying with strangers. When men once became akin to Tobiah, they soon became sworn to him. A sinful love leads to a sinful league. The enemy of souls employs many instruments, and forms many projects, to bring reproach on the active servants of God, or to take them from their work. But we should follow the example of Him who laid down his life for the sheep. Those that simply cleave to the Lord and his work will be supported.
