NEH 6:3

3 Therefore I sent messengers to them, and I said, I make a great work, and I may not go down therefore, (or And so I sent messengers to them, and I said, I am doing important work here, and so I cannot go down there), lest peradventure it be done recklessly or lest peradventure it be done negligently, when I come, and go down to you.
