The grave (Sheol in Hebrew) is personified as a predator, perhaps a lion or wolf. The rich, who were the wicked in previous verses (5-6, 12) are being guided by the predator Grave to itself where it will feed on them for eternity. Like sheep, they do not know that they are led to the grave while they feed in rich lands. They do not contemplate their destiny for they trust in themselves and the riches they acquire.
The wicked rich’s bodies will remain buried while the upright rule over them in Jesus’ kingdom starting at the resurrection of the dead. Jesus promised, “To him who overcomes and does my will to the end, I will give authority over the nations– ‘He will rule them with an iron scepter; he will dash them to pieces like pottery’– just as I have received authority from my Father.” (Revelation 2:26-27)
The author in verse 15 makes a personal confession that is common to all the saints. “God will redeem my life from the grave; he will surely take me to himself.” Though oppressed by the wicked and do not have great wealth the righteous do have a firm belief that they will be redeemed. As the prophet Daniel recorded, “Multitudes who sleep in the dust of the earth will awake: some to everlasting life, others to shame and everlasting contempt. Those who are wise will shine like the brightness of the heavens, and those who lead many to righteousness, like the stars for ever and ever.” (Daniel 12:2-3) Do not lose hope.
