Jeremia 10:5

We may conjecture that the prophecy of this chapter was delivered after the first captivity, in the time of Jeconiah or Jehoiachin, when many were carried away to Babylon; for it has a double reference: - I. To those that were carried away into the land of the Chaldeans, a country notorious above any other for idolatry and superstition; and they are here cautioned against the infection of the place, not to learn the way of the heathen (Jer 10:1, Jer 10:2), for their astrology and idolatry are both foolish things (Jer 10:3-5), and the worshippers of idols brutish (Jer 10:8, Jer 10:9). So it will appear in the day of their visitation (Jer 10:14, Jer 10:15). They are likewise exhorted to adhere firmly to the God of Israel, for there is none like him (Jer 10:6, Jer 10:7). He is the true God, lives for ever, and has the government of the world (Jer 10:10-13), and his people are happy in him (Jer 10:16). II. To those that yet remained in their own land. They are cautioned against security, and told to expect distress (Jer 10:17, Jer 10:18) and that by a foreign enemy, which God would bring upon them for their sin (Jer 10:20-22). This calamity the prophet laments (Jer 10:19) and prays for the mitigation of it (Jer 10:23-25).

10:5 Just as scarecrows in a garden can do nothing more than scare ignorant birds, idols are feared only by ignorant people.
