So the LORD alone did lead him, and there was no strange god with him.

Wesley's Notes

32:12 Did lead them - When they were shut up in Egypt as in their nest whence they durst not venture to fly nor stir, he taught and encouraged and enabled them to fly out from that bondage, he dealt tenderly with them, bearing with their infirmities, keeping them from all harms. With him - To assist him at that work or to deliver them. The more unworthy they in giving to idols a share in that worship which they owe to God only.

Matthew Henry's Concise Commentary

32:7-14 Moses gives particular instances of God's kindness and concern for them. The eagle's care for her young is a beautiful emblem of Christ's love, who came between Divine justice and our guilty souls, and bare our sins in his own body on the tree. And by the preached gospel, and the influences of the Holy Spirit, He stirs up and prevails upon sinners to leave Satan's bondage. In ver. 13,14, are emblems of the conquest believers have over their spiritual enemies, sin, Satan, and the world, in and through Christ. Also of their safety and triumph in him; of their happy frames of soul, when they are above the world, and the things of it. This will be the blessed case of spiritual Israel in every sense in the latter day.
