Isaiah 7:23 - Ellicott's Commentary On The Whole Bible

Where there were a thousand vines at a thousand silverlings. — The words seem to contain an allusive reference to Song of Solomon 8:11, and are therefore worth noting as bearing on the date of that book. There, however, the sum represents the annual produce of the vineyard, here the rent of the vines at a shekel each, a high rent apparently, and indicating a choice quality of vine. The costly vineyards of the hills of Judah should be left to run wild without a keeper (Isaiah 5:10), and thorns and briers would rapidly cover it. “Silverling” was an old English word for any silver coin, and appears in Tyndale’s version of Acts 19:19, and Coverdale’s of Judges 9:4; Judges 16:5; here it stands for “shekel.” The modern rent is said to be a piastre (2¼d.) for each vine; the shekel was worth 2s. 3 d. (Kay).
