In this passage, the prophet Isaiah addresses the Israelites, who have turned away from worshiping God to idolizing inanimate objects, symbolized by smooth stones in ravines. These idols have become their 'portion' and 'lot,' indicating that the people have chosen them as their source of security and blessing. By offering drink and grain offerings to these idols, the Israelites demonstrate a significant level of devotion and sacrifice, which should have been reserved for God alone.
The rhetorical question at the end of the verse, 'Should I relent?' suggests God's disappointment and the seriousness of their idolatry. It implies that God is questioning whether He should withhold His judgment despite their actions. This verse serves as a powerful reminder of the importance of directing our devotion and worship towards God, who is the true source of life and blessing. It encourages believers to examine their hearts and ensure that their faith and trust are placed in God rather than in material possessions or false idols.
