15 For he brought a distant nation against them, a nation ruthless and of a strange language, which had no respect for the aged and no pity for a child. 16 They led away the widow's beloved sons, and bereaved the lonely woman of her daughters. 17 But I, how can I help you? 18 For he who brought these calamities upon you will deliver you from the hand of your enemies. 19 Go, my children, go; for I have been left desolate. 20I have taken off the robe of peace and put on sackcloth for my supplication; I will cry to the Everlasting all my days.21 Take courage, my children, cry to God, and he will deliver you from the power and hand of the enemy. 22For I have put my hope in the Everlasting to save you, and joy has come to me from the Holy One, because of the mercy that will soon come to you from your everlasting savior.23 For I sent you out with sorrow and weeping, but God will give you back to me with joy and gladness forever. 24 For as the neighbors of Zion have now seen your capture, so they soon will see your salvation by God, which will come to you with great glory and with the splendor of the Everlasting. 25 My children, endure with patience the wrath that has come upon you from God. Your enemy has overtaken you, but you will soon see their destruction and will tread upon their necks.

Athanasius Discourse Against the Arians 4
And where the sacred writers say, 'Who exists before the ages,' and 'By whom He made the ages,' they thereby as clearly preach the eternal and everlasting being of the Son, even while they are designating God Himself. Thus, if Isaiah says, 'The Everlasting God, the Creator of the ends of the earth' and Susanna said, 'O Everlasting God' and Baruch wrote, 'I will cry unto the Everlasting in my days,' and shortly after, 'My hope is in the Everlasting, that He will save you, and joy has come unto me from the Holy One' yet forasmuch as the Apostle, writing to the Hebrews, says, 'Who being the radiance of His glory and the Expression of His Person' and David too in the eighty-ninth Psalm, 'And the brightness of the Lord be upon us,' and, 'In Your Light shall we see Light ,' who has so little sense as to doubt of the eternity of the Son?
