Israel is a luxuriant vine that puts forth his fruit. According to the abundance of his fruit he has multiplied his altars. As their land has prospered, they have adorned their sacred stones.
the more altars he built … he improved his pillars. It was just as Moses had warned (Deuteronomy 8:11-14). Abundance is risky; God’s people could not handle it (cf. Proverbs 30:7-9).
