(18) Sworn unto him.--Shechaniah was of the family of Arah, which had come over with Zerubbabel (Ezra 2:5). Tobiah had married his daughter, and Tobiah's son had married a daughter of Meshullam, one of the builders of the wall (Nehemiah 3:4; Nehemiah 3:30). This family connection led to a conspiracy by oath to thwart the governor. The names of Tobiah and his son are Hebrew; and it is probable that, though naturalised Ammonites, they were of Hebrew extraction. This renders it easier to understand the facility with which the affinity was contracted.

Verse 18. - He was the son-in-law of Shechaniah. Rather, "related by marriage to Shechaniah"- perhaps, but not certainly, by having married his daughter. Son of Arah. Member, i.e., of the family, called the Beni-Arah, which had returned with Zerubbabel (Ezra 2:5; Nehemiah 7:10). Meshullam the son of Berechiah is mentioned in ch. 3. as repairing two portions of the wall (vers. 4, 30).

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.For there were many in Judah sworn unto him,.... To Tobiah, who not only in a private manner corresponded with him by letters, but bound themselves by an oath to him to be true to his interest, and do as he should advise them:

because he was the son in law of Shechaniah, the son of Arah; of a family that came up with Zerubbabel from the captivity, Ezra 2:5 and very probably of considerable note:

and his son Johanan had taken the daughter of Meshullam the son of Berechiah; a very eminent person, concerned in building the wall, Nehemiah 3:4.
