A stock. Literally, “a tree,” or “a piece of wood,” here representing the material from which an idol is made (see Isa. 40:20; 44:9; 45:20; Hosea 4:12).
Thou art my father. How utterly stupid to attribute the production and sustenance of life to a piece of wood. The Lord placed the vanity of idol worship in its strongest light in order to emphasize the unpardonable flagrancy of Israel’s transgression.
A stone. That is, an idol made of stone (see Jer. 3:9; Deut. 4:28; 28:36, 64; 29:17; 2 Kings 19:18; Eze. 20:32).
Thou hast. The pronoun translated “thou” is feminine; hence, the stone is addressed as the mother.
Turned their back. A gesture of contempt and aversion (see chs. 7:24; 18:17; 32:33).
Time of their trouble. Compare Ps. 78:34; Isa. 26:16. Trouble often brings men to their senses (see Hosea 5:15).
