13:12 God would not forget Israel's sins. Its iniquities were rolled up (Heb. sarar) in a bundle like a scroll and stored up (Heb. sapan) like a treasure. They stood as hard evidence that condemned the nation.
13:13 Israel was like a baby that refused to come out of its mother's womb in the sense that it refused to leave its comfortable sin. Despite the mother's (God's) strenuous efforts to bring the child into freedom, Israel refused to repent. This was evidence that Israel was a foolish child. She would die rather than leave her sins apparently feeling that the proper time for repenting was not yet.
13:14 The Lord asked rhetorically if He would buy the Israelites back out of death's hand. Would He pay a price for their redemption? No, compassion would be hidden from His sight; He would have no pity on them. He appealed for death (like a thorn bush) to torment the Israelites, as though thorns tore their flesh. He called on the grave (as a hornet) to sting them fatally.
Later in history God did provide a ransom for His people from the power of the grave, and He redeemed them from death. He did this when Jesus Christ died on the cross and rose again. God's future redemptive work for His people meant that death would not be the end for Israel even though judgment in the near future was inevitable.
The Apostle Paul quoted the famous couplet in this verse in 1 Corinthians 15:15:55 and applied it to the effect of Christ's redemption on all of God's people. Because God did provide a ransom and redeemed His people, death and the grave are not the final judgment and home of the believer. God has a glorious future beyond His punishment for sin for His own, both for national Israel and for Christians. Paul's use of this passage does not support the view that the church fulfills God's promises concerning Israel. Here in Hosea the promise is that Israel would indeed suffer death and the grave, not that she would escape it. Paul turned the passage around and showed that Jesus Christ's resurrection overcame the judgment and death that are inevitable for sinners.
