When Nehemiah had prayed for the relief of his countrymen, and perhaps in David's words, Ps 51:18, he did not sit still and say, "Let God now do his own work, for I have no more to do;" but set himself to do what he could towards it; and here we find that the people were of one heart with Nehemiah. Our prayers must be seconded with our serious endeavours, or else we mock God. Nearly four months had passed, namely, from Chisleu to Nisan (November to March), before Nehemiah made his application to the king for leave to go to Jerusalem; either because the winter was not a proper time for such a journey, and he would not make a motion till he could pursue it, or because it was so long before his month of waiting upon the king came, and there was no coming into his presence until called for, Es 4:11. We are not thus limited to certain moments in our addresses to the King of kings, but have liberty of access to him at all times; to the throne of grace we never come unseasonably.
