After this phrase with the Persian flavour, Nehemiah adds expressions borrowed from the Hebrew Book of Deuteronomy, a book with ideas and words from which his prayer is saturated throughout. God is described on the one hand as "great and terrible." and on the other hand as keeping "covenant and mercy for them that love Him and observe His commandments."[140] The Deuteronomist adds "to a thousand generations"--a clause not needed by Nehemiah, who is now only concerned with one special occasion. The first part of the description is in harmony with the new and exalted title of God, and therefore it fits in well here. It is also suitable for the circumstances of the prayer, because in times of calamity we are impressed with the power and terror of Providence. There is another side to these attributes, however. The mention of them suggests that the sufferers have not fallen into the hand of man. Hanani and his fellow-Jews made no allusion to a Divine action; they could not see beyond the jealousy of neighbouring people in the whole course of events. But Nehemiah at once recognised God's hand. This perception would calm him as he watched the solemn movement of the drama carried up into heavenly regions. Then, aided by the cheering thought which came to him from the book of Divine revelation on which his prayer was moulded, Nehemiah turns to the covenant-keeping mercy of God. The covenant which he appeals to here must be that of the Book of Deuteronomy; his subsequent references to the contents of that book make this quite clear. [140] Neh. i. 5. See Deut. vii. 9. It is important to see that Nehemiah recognises the relation of God's mercy to His covenant. He perceives that the two go together, that the covenant does not dispense with the need of mercy any more than it forecloses the action of mercy. When the covenant people fall into sin, they cannot claim forgiveness as a right; nor can they ever demand deliverance from trouble on the ground of their pact with God. God does not bargain with His children. A Divine covenant is not a business arrangement, the terms of which can be interpreted like those of a deed of partnership, and put into force by the determinate will of either party. The covenant is, from the first, a gracious Divine promise and dispensation, conditioned by certain requirements to be observed on man's side. Its very existence is a fruit of God's mercy, not an outcome of man's haggling, and its operation is just through the continuance of that mercy. It is true a promise, a sort of pledge, goes with the covenant; but that is a promise of mercy, a pledge of grace. It does not dispense with the mercy of God by converting what would otherwise be an act of pure grace on His part into a right which we possess and act upon of our own sole will. What it does is to afford a channel for the mercy of God, and to assure us of His mercy, which, however, remains mercy throughout.
