On the sabbath. The prohibition of commerce on the Sabbath, though not specifically mentioned in the fourth commandment, is implicit in it, and is certainly included in regulations pertaining to that day. Amos 8:5 implies this prohibition, as well as Isa. 58:13 and Jer. 17:19-27. The earliest non-Biblical evidence for the observance of the weekly Sabbath among the Jews comes from the 5th century B.C., from Elephantine in Egypt. This mention of the Sabbath is found on ostraca, or potsherds, that is, pieces of broken pottery commonly used as inexpensive writing material.
The holy day. Rather, “a holy day,” meaning that the people bound themselves to refrain from trading not only on the Sabbath but on any holy day.
Leave the seventh year. An abbreviated statement of the law concerning the sabbatical year (Ex. 23:10, 11), according to which the land was to lie untilled and unsown during that year. This law had frequently been neglected during the times of the monarchy, and its neglect was one of the sins the Captivity was expressly intended to punish (2 Chron. 36:21). It now appears that after the return this regulation had again been disobeyed.
Debt. For comment, see on ch. 5:12-13.
