I will meet them like a bear that is bereaved of her cubs, And will tear the covering of their heart. And there I will devour them like a lioness. The wild animal will tear them.
Paul probably was thinking of this passage in Hosea when he closed off his first epistle to the Corinthians in chapter 15. And he said, "And then shall be brought to pass the same." The same probably being this reference here in Hosea "O death, where is thy sting? O grave, where is thy victory? For the sting of death is sin, but thanks be unto God that through Jesus Christ we have victory over sin" ( 1 Corinthians 15:55-57 ). So that sting of death has been removed through Jesus Christ and he's no doubt referring here to God's destruction of death and grave as a fearful last enemy of man.
