Genesis 6:4

Became - Was exactly suited for; was fitting.

Renown - A great name or well-known.

There were giants in the earth - נפלים nephilim, from נפל naphal, "he fell." Those who had apostatized or fallen from the true religion. The Septuagint translate the original word by γιγαντες, which literally signifies earth-born, and which we, following them, term giants, without having any reference to the meaning of the word, which we generally conceive to signify persons of enormous stature. But the word when properly understood makes a very just distinction between the sons of men and the sons of God; those were the nephilim, the fallen earth-born men, with the animal and devilish mind. These were the sons of God, who were born from above; children of the kingdom, because children of God. Hence we may suppose originated the different appellatives given to sinners and saints; the former were termed γιγαντες, earth-born, and the latter, ἁγιοι, i.e. saints, persons not of the earth, or separated from the earth.

The same became mighty men - men of renown - גברים gibborim, which we render mighty men, signifies properly conquerors, heroes, from גבר gabar, "he prevailed, was victorious." and אנשי השם anshey hashshem, "men of the name," ανθρωποι ονομαστοι, Septuagint; the same as we render men of renown, renominati, twice named, as the word implies, having one name which they derived from their fathers, and another which they acquired by their daring exploits and enterprises.

It may be necessary to remark here that our translators have rendered seven different Hebrew words by the one term giants, viz., nephilim, gibborim, enachim, rephaim, emim, and zamzummim; by which appellatives are probably meant in general persons of great knowledge, piety, courage, wickedness, etc., and not men of enormous stature, as is generally conjectured.

Two classes of men, with strong hand and strong will, are here described. "The giants," the well-known men of great stature, physical force, and violent will, who were enabled by these qualities to claim and secure the supremacy over their fellow-men. "Had been in the land in those days." In the days when those intermarriages were beginning to take place, the warriors were asserting the claim of might. Violence and rapine were becoming rampant in the land. "And after that." The progeny of the mixed marriages were the second and subsequent class of leading men. "The sons of God" are here contradistinguished from the "nephilim, or giants," who appear therefore to have belonged to the Cainites. The offspring of these unhallowed unions were the heroes, the gallants, the mighty men, the men of renown. They were probably more refined in manners and exalted in thought than their predecessors of pure Cainite descent. "Men of name," whose names are often in men's mouths, because they either deserved or required to be named frequently on account of their influential or representative character. Being distinguished from the common herd by prominent qualities or memorable exploits, they were also frequently marked out by a special name or surname, derived from such trait of character or deed of notoriety. "Of old" (מעולם mē'ôlām). This has been sometimes explained "of the world," in the sense of αἰών aiōn; but the meaning is too late for the present passage. The phrase uniformly means "of old," covering a more or less extensive length of time. This note of time implies a writer probably after the deluge, who could speak of antediluvian affairs, as happening of old.

It is remarkable that we have no hint of any kind of government in the antediluvian world. It is open to us to suppose that the patriarchal polity would make its appearance, as it is an order based upon natural relations. But it is possible that God himself, being still present and manifest, was recognized as the governor. To him offerings were brought, and he deals with Cain on his first and second transgression. In that case the lawless violence of the strong and willful is to be regarded as rebellion, not only against the patriarchal rule, but the divine supremacy. A notice of civil law and government would not of course affect the authority of the book. But the absence of such notice is in favor of its divine origin. It is obvious that higher things than these have the attention of the sacred writer.

6:4 There were giants, and men of renown - They carried all before them,
1. With their great bulk, as the sons of Anak, Nu 13:33, and,
2. With their great name, as the king of Assyria, Isa 37:11. Thus armed, they daringly insulted the rights of all their neighbours, and trampled upon all that is just and sacred.
