Wisdom of Solomon 18:15
13 For whereas they would not believe any thing by reason of the enchantments; upon the destruction of the firstborn, they acknowledged this people to be the sons of God. 14 For while all things were in quiet silence, and that night was in the midst of her swift course, 15 Thine Almighty word leaped down from heaven out of thy royal throne, as a fierce man of war into the midst of a land of destruction, 16 And brought thine unfeigned commandment as a sharp sword, and standing up filled all things with death; and it touched the heaven, but it stood upon the earth. 17 Then suddenly visions of horrible dreams troubled them sore, and terrors came upon them unlooked for. 18 And one thrown here, and another there, half dead, shewed the cause of his death.
Hebrews 4:12
10 For the one who enters God’s rest has also rested from his works, just as God did from his own works. 11 Thus we must make every effort to enter that rest, so that no one may fall by following the same pattern of disobedience. 12 For the word of God is living and active and sharper than any double-edged sword, piercing even to the point of dividing soul from spirit, and joints from marrow; it is able to judge the desires and thoughts of the heart. 13 And no creature is hidden from God, but everything is naked and exposed to the eyes of him to whom we must render an account. 14 Therefore since we have a great high priest who has passed through the heavens, Jesus the Son of God, let us hold fast to our confession. 15 For we do not have a high priest incapable of sympathizing with our weaknesses, but one who has been tempted in every way just as we are, yet without sin.
Notes and References
"... Philo uses similar imagery in reference to the Logos; for example, he describes the Logos as a flaming sword (φλογίνη ῥομφαία) in reference to the angel of Genesis. He also speaks of a “severing Logos” (λόγος τομεύς) as a cosmic principle which is intelligible to human reason. However, this similarity in language between Hebrews and Philo is most likely explained by the presence of “logos/sword” imagery in the Old Testament. Both Philo and Hebrews are taking advantage of a preexisting tradition. This tradition can be seen, for example, in such passages where the tongue is portrayed as a sword (compare Is 49:2, Ps 57:5). The “word” as a sword could be considered an extension of this imagery. More relevant to this study is the description of the Logos found in Wisdom 18:14-16, where we read that, “while gentle silence enveloped all things, and night in its swift course was now half gone, thy all-powerful word (λόγος) leaped from heaven, from the royal throne, into the midst of the land that was doomed, a stern warrior carrying the sharp sword (ξίφος) of thy authentic command.” Such a passage demonstrates that the logos /sword imagery of Hebrews 4:12 need not be directly inspired by Philo ..."
