“Nor was Mary less than was befitting the mother of Christ. When the apostles fled, she stood before the cross and with reverent gaze beheld her Son's wounds, for she awaited not her child's death but the world's salvation. Or perhaps that "regal chamber" knew that through her Son's death would be the world's redemption, and through her own death she thought she would give herself for the common good. But Jesus had no need of a helper in redeeming all, for he saved all without a helper. Therefore he says, "I have become as a man without help, free among the dead." Indeed, he received the devotion of his parent, but he did not seek another's aid.”

“Next, David made it clear that Christ would be buried when he said, "They have put me in the lowest pit in the dark places and in the shadow of death." Nor was David silent about the spices used on his shroud. Since the women brought myrrh, spice and cassia, hear what the prophet said: "Your robes are all fragrant with myrrh, spice and cassia, and with them the daughters of kings gladdened you in your honor." See how he also predicted that Christ would rise again. "You will not leave my soul in hell, nor will you allow your holy one to see corruption." Isaiah expressed the same thing in a different way. For he said, "The Lord wishes to cleanse him from his wounds, to show him light, to justify the righteous one who has served many well."”

“"Free among the dead" [Psalm 88:5]. In these words our Lord's Person is most clearly shown: for who else is free among the dead but He who though in the likeness of sinful flesh is alone among sinners without sin? [Romans 8:3] ...He therefore, "free among the dead," who had it in His power to lay down His life, and again to take it; from whom no one could take it, but He laid it down of His own free will; who could revive His own flesh, as a temple destroyed by them, at His will; who, when all had forsaken Him on the eve of His Passion, remained not alone, because, as He testifies, His Father forsook Him not; [John 8:29] was nevertheless by His enemies, for whom He prayed, who knew not what they did, ...counted "as one who has no help; like them that are wounded, and lie in the grave." But he adds, "Whom thou dost not yet remember:" and in these words there is to be remarked a distinction between Christ and the rest of the dead. For though He was wounded, and when dead laid in the tomb, [Matthew 27:50, 60] yet they who knew not what they were doing, or who He was, regarded Him as like others who had perished from their wounds, and who slept in the tomb, who are as yet out of remembrance of God, that is, whose hour of resurrection has not yet arrived. For thus the Scripture speaks of the dead as sleeping, because it wishes them to be regarded as destined to awake, that is, to rise again. But He, wounded and asleep in the tomb, awoke on the third day, and became "like a sparrow that sits alone on the housetop," that is, on the right hand of His Father in Heaven: and now "dies no more, death shall no more have dominion over Him." [Romans 6:9] Hence He differs widely from those whom God has not yet remembered to cause their resurrection after this manner: for what was to go before in the Head, was kept for the Body in the end. God is then said to remember, when He does an act: then to forget, when He does it not: for neither can God forget, as He never changes, nor remember, as He can never forget. "I am counted" then, by those who know not what they do, "as a man that has no help:" while I am "free among the dead," I am held by these men "like them that are wounded, and lie in the grave." Yet those very men, who account thus of Me, are further said to be "cut away from Your hand," that is, when I was made so by them, "they were cut away from Your hand;" they who believed Me destitute of help, are deprived of the help of Your hand: for they, as he says in another Psalm, have dug a pit before me, and are fallen into the midst of it themselves. I prefer this interpretation to that which refers the words, "they are cut away from Your hand," to those who sleep in the tomb, whom God has not yet remembered: since the righteous are among the latter, of whom, even though God has not yet called them to the resurrection, it is said, that their "souls are in the hands of God," [Wisdom 3:1] that is, that "they dwell under the defence of the Most High; and shall abide under the shadow of the God of Heaven." But it is those who are cut away from the hand of God, who believed that Christ was cut off from His hand, and thus accounting Him among the wicked, dared to slay Him.”

“"They laid Me in the lowest pit" [Psalm 88:6], that is, the deepest pit. For so it is in the Greek. But what is the lowest pit, but the deepest woe, than which there is none more deep? Whence in another Psalm it is said, "You brought me out also of the pit of misery." "In a place of darkness, and in the shadow of death," whiles they knew not what they did, they laid Him there, thus deeming of Him; they knew not Him "whom none of the princes of this world knew." [1 Corinthians 2:8] By the "shadow of death," I know not whether the death of the body is to be understood, or that of which it is written, "That they walked in darkness and in the land of the shadow of death, a light is risen on them," [Isaiah 9:2] because by belief they were brought from out of the darkness and death of sin into light and life. Such an one those who knew not what they did thought our Lord, and in their ignorance accounted Him among those whom He came to help, that they might not be such themselves.”

“Thou hast laid me in the lowest pit,.... The Targum interprets it of "captivity which was like unto the lowest pit;'' and so Jarchi and Kimchi. Some understand it of a prison or dungeon, into which the psalmist was put; it may be interpreted of the pit of the grave, into which Christ was laid; though he continued in it not so long as to see corruption; from that prison and judgment he was quickly taken, Psa 16:10, "in darkness"; both corporeal and spiritual, Mat 27:45, and it is in the Hebrew text "in darknesses" (k), denoting both: in the deeps; in the deep waters of affliction, sorrows, and sufferings; see Psa 69:1. The allusion is to a dark and deep pit, under ground, such as in the eastern countries they used to put their captives and prisoners into in the night, and take them out in the morning; and which custom continues still among the Turks. Leo Africanus (l) says he has seen three thousand Christian captives together, clothed in a woollen sack, and chained to one another; and in the night put into pits or ditches under ground; see Zac 9:11. (k) "in loca tenebrosa", Tigurine version, Musculus; "in tenebrosissimis", Junius & Tremellius; "in densis tenebris", Piscator; "in caligines, vel obscuritates", Gejerus.
