Wisdom of Solomon 10:20
18 She brought them over the Red Sea, and led them through deep waters; 19 but she drowned their enemies, and cast them up from the depth of the sea. 20 Therefore the righteous plundered the ungodly; they sang hymns, O Lord, to your holy name, and praised with one accord your defending hand; 21 for wisdom opened the mouths of those who were mute, and made the tongues of infants speak clearly.
Josephus Antiquities of the Jews Book 2 16:6
6 On the next day Moses gathered together the weapons of the Egyptians, which were brought to the camp of the Hebrews, by the current of the sea, and the force of the winds assisting it: and he conjectured that this also happened by divine providence, that so they might not be destitute of weapons. So when he had ordered the Hebrews to arm themselves with them, he led them to mount Sinai, in order to offer sacrifice to God, and to render oblations for the salvation of the multitude, as he was charged to do beforehand.
Notes and References
"... there are also elements that Pseudo-Solomon uses to supplement the biblical depiction of his wholly righteous and wicked figures, these include (1) Cain’s anger in Wisdom of Solomon 10:3; (2) Cain as a cause for the Flood in verse 4; (3) the unripe fruit that is a testimony of Sodom’s wickedness in verse 7; (4) the “unbelief” of Lot’s wife in verse 7; (5) an explanation of the memorial of Sodom’s wickedness in verse 8; and (6) the Israelites’ plundering of the Egyptians as reimbursement for their labors in verse 17. These omissions and additions contribute to the idealized picture of the righteous and wicked figures in chapter 10. Just as Pseudo-Solomon occasionally leaves out scriptural details and adds others to enhance the desired qualities of his examples, he does the same so as to emphasize the saving activity of Lady Wisdom and her praiseworthiness ..."
