Noadiah is not elsewhere mentioned. The examples of Miriam, Deborah, Huldah, and Anna, show that the prophetical gift was occasionally bestowed upon women (2 Kings 22:14 note).

And on the prophetess Noadiah - Whether this was a prophet or prophetess, we cannot tell; the Hebrew text only makes her a prophetess; all the versions have Noadiah the prophet, except the Arabic which has Younadaa the prophet. I think the ה he at the end of נביאה nebiah is a mistake, and that we should read Noadiah the prophet.

My God, think thou on Tobiah and Sanballat according to these their works,.... Their wicked counsels and schemes, and not only confound and disappoint them, but reward them as they deserve:

and on the prophetess Noadiah: whom Aben Ezra takes to be the same with Shemaiah, because he said, "let us meet", &c. Nehemiah 6:10, but no doubt it is the name of a woman, a false prophetess, and was hired, and in the same scheme with Shemaiah:

and the rest of the prophets that would have put me in fear; and so put him on leaving the people, and the work he was engaged in, and flee for his safety; it seems there were more than are by name mentioned, who sought to discourage and intimidate him.

My God, think thou upon Tobiah and Sanballat according to these their works, and on the {g} prophetess Noadiah, and the rest of the prophets, that would have put me in fear.

(g) Grief caused him to pray against such, who under the pretence of being the ministers of God, were adversaries to his glory, and went about to overthrow his Church, declaring also by this that where there is one true minister of God, the devil has many hirelings.

6:14 My God, and c. - This prayer we are not to imitate.

6:10-14 The greatest mischief our enemies can do us, is, to frighten us from our duty, and to lead us to do what is sinful. Let us never decline a good work, never do a bad one. We ought to try all advice, and to reject what is contrary to the word of God. Every man should study to be consistent. Should I, a professed Christian, called to be a saint, a child of God, a member of Christ, a temple of the Holy Ghost, should I be covetous, sensual, proud, or envious? Should I yield to impatience, discontent, or anger? Should I be slothful, unbelieving, or unmerciful? What effects will such conduct have upon others? All that God has done for us, or by us, or given to us, should lead us to watchfulness, self-denial, and diligence. Next to the sinfulness of sin, we should dread the scandal.
