And it came to pass, that when the Jews which dwelt by them came, they said unto us {f} ten times, {g} From all places whence ye shall return unto us they will be upon you.

(f) That is, often.

(g) They who brought the tidings said this, when you leave your work, and go either to eat or to rest, your enemies will assail you.

Wesley's Notes

4:12 By them - Or, among them: whereby they came to the knowledge of their counsels. Tho' these had not zeal enough to help in the work, yet they had some concern for their brethren. Ten tribes - Very often, a certain number for an uncertain. Be upon you - They will invade you every way, by which we can come to you, or you to us; therefore keep watches on every side.

King James Translators' Notes

From all...: or, That from all places ye must return to us

Matthew Henry's Concise Commentary

4:7-15 The hindering good work is what bad men aim at, and promise themselves success in; but good work is God's work, and it shall prosper. God has many ways of bringing to light, and so of bringing to nought, the devices and designs of his church's enemies. If our enemies cannot frighten us from duty, or deceive us into sin, they cannot hurt us. Nehemiah put himself and his cause under the Divine protection. It was the way of this good man, and should be our way. All his cares, all his griefs, all his fears, he spread before God. Before he used any means, he made his prayer to God. Having prayed, he set a watch against the enemy. If we think to secure ourselves by prayer, without watchfulness, we are slothful, and tempt God; if by watchfulness, without prayer, we are proud, and slight God: either way, we forfeit his protection. God's care of our safety, should engage and encourage us to go on with vigour in our duty. As soon as a danger is over, let us return to our work, and trust God another time.
