And Israel sent messengers. The second narration, which I have subjoined from Deuteronomy, is the fuller; nevertheless, a question arises from it, for what reason this embassy was sent to king Sihon, whose kingdom was already devoted to the Israelites: for it seems to be altogether inconsistent to offer conditions of peace when war is decreed. God commands His people to take up arms: He declares that they shall be victorious, so as to occupy the land of Sihon by right of war; what, then, can be more absurd than to request of him that they might pass through his land in peace? If this attempt were made by Moses without the command of God, such an excess of kindness was not devoid of guilt, inasmuch as it was an act of much temerity to promise what God had appointed otherwise. But, if we should say that the messengers went with the authority, and at the command of God, under what pretext shall the deceptiveness of the act be excused? for it is very improper to flatter with soothing words and promises those whom you have destined to destruction. The conclusion I come to is, that although the event was not unknown to God, still the embassy was sent, nevertheless, by his command and decree, in order to lay open the obstinate ferocity of the nation. But, since the secret judgments of God far surmount our senses, let us learn to reverence their height; and let this sober view restrain our boldness like a rein, viz., that although the reason for the works of God be unknown to us, still it always exists with Him. God knew that the messengers would speak to the deaf, and yet it is not in vain that He bids them go; for, since the kingdom of Sihon was not properly included in the promised land, it was not lawful for the children of Israel to make war upon it until they had been provoked by an unjust refusal. Thus, then, I connect the history. Before they had been assured at God's command of the event, and the victory, they sent the messengers, who demanded that a pacific passage should be accorded to them; and that then the permission to have recourse to arms was granted. If any prefer to think that, before Moses attempted to preserve peace, he had been made acquainted with all that would occur, I will not contend the point; but I deem it more probable that he had expectations of the peace which he sought, because the judgment of God had not yet been declared. If, therefore, Sihon had allowed himself to be propitiated, Moses would never have dared to deal with him as an enemy; but, he rather simply and honestly promised peace, which he intended to preserve; God, however, had otherwise appointed, as the event presently shewed. Still He was not inconsistent with Himself, or variable, in sending the messengers to an irreclaimable and obstinately perverse man; for thus was all excuse taken away when he had voluntarily provoked to war a people who were ready and willing to maintain peace and equity. But rather may we see in this history, as in a glass, that, whilst God earnestly invites the reprobate to repentance and the hope of salvation, He has no other object than that they may be rendered inexcusable by the detection of their impiety. Hence is their ignorance refuted, who gather from this that it is free for all promiscuously to embrace God's grace, because its promulgation (doctrina) is common, and directed to all without exception; as if God was not aware of what Sihon would answer when He would have him attracted to equity by friendly and peaceful words; or as if, on his free will, the purpose of God was suspended as to the war, which was soon after carried forward by His decree.
But inasmuch as what is here briefly recorded, would be obscure in itself, we must explain it by the other narrative, where it is thus written, --
