'Cast image' in the Bible

Nevertheless, I have ever since the beginning showed thee of things for to come, and declared them unto thee before they came to pass: that thou shouldest not say, "Mine Idol hath done it; my carved or cast image hath showed it."

What help then will the Image do, whom the workman hath fashioned? Or the vain cast Image, wherein because the craftsmen putteth his trust, therefore maketh he dumb Idols?
