Jeremiah 17:4

Thou, even thyself. — Literally, in or by thyself, an emphatic form for expressing loneliness and abandonment.

Shalt discontinue... — The word was a half-technical one, used to describe the act of leaving lands untilled and releasing creditors in the sabbatical year (Exodus 23:11; Deuteronomy 15:2). The land would have its rest now, would “enjoy its Sabbaths” (Leviticus 26:34; 2 Chronicles 36:21), though Judah had failed in obedience to the Law which prescribed them. For the rest of the verse, see Note on Jeremiah 15:14.
