Behold, I set before you - a blessing and a curse - If God had not put it in the power of this people either to obey or disobey; if they had not had a free will, over which they had complete authority, to use it either in the way of willing or nilling; could God, with any propriety, have given such precepts as these, sanctioned with such promises and threatenings? If they were not free agents, they could not be punished for disobedience, nor could they, in any sense of the word, have been rewardable for obedience. A Stone is not rewardable because, in obedience to the laws of gravitation, it always tends to the center; nor is it punishable be cause, in being removed from that center, in its tending or falling towards it again it takes away the life of a man.

That God has given man a free, self-determining Will, which cannot be forced by any power but that which is omnipotent, and which God himself never will force, is declared in the most formal manner through the whole of the sacred writings. No argument can affect this, while the Bible is considered as a Divine revelation; no sophistry can explain away its evidence, as long as the accountableness of man for his conduct is admitted, and as long as the eternal bounds of moral good and evil remain, and the essential distinctions between vice and virtue exist. If ye will obey, (for God is ever ready to assist), ye shall live; if ye will disobey and refuse that help, ye shall die. So hath Jehovah spoken, and man cannot reverse it.

Josiah, a Pattern for the Ignorant.
"Because thine heart was tender, and thou hast humbled thyself before the Lord, when thou heardest what I spake against this place, and against the inhabitants thereof, that they should become a desolation and a curse, and hast rent thy clothes, and wept before Me; I also have heard thee, saith the Lord. Behold therefore, I will gather thee unto thy fathers, and thou shalt be gathered into thy grave in peace; and thine eyes shall not see all the evil which I will bring upon this place."--2 Kings …

The Old Testament Canon from Its Beginning to Its Close.
The first important part of the Old Testament put together as a whole was the Pentateuch, or rather, the five books of Moses and Joshua. This was preceded by smaller documents, which one or more redactors embodied in it. The earliest things committed to writing were probably the ten words proceeding from Moses himself, afterwards enlarged into the ten commandments which exist at present in two recensions (Exod. xx., Deut. v.) It is true that we have the oldest form of the decalogue from the Jehovist …

Deuteronomy
Owing to the comparatively loose nature of the connection between consecutive passages in the legislative section, it is difficult to present an adequate summary of the book of Deuteronomy. In the first section, i.-iv. 40, Moses, after reviewing the recent history of the people, and showing how it reveals Jehovah's love for Israel, earnestly urges upon them the duty of keeping His laws, reminding them of His spirituality and absoluteness. Then follows the appointment, iv. 41-43--here irrelevant (cf. …
