Charles Ellicott Commentary Jeremiah 34:14

"At the end of seven years ye shall let go every man his brother that is a Hebrew, that hath been sold unto thee, and hath served thee six years, thou shalt let him go free from thee: but your fathers hearkened not unto me, neither inclined their ear." — Jeremiah 34:14 (ASV)

At the end of seven years ... —The immediate context, when he hath served thee six years, shows that the liberation was intended to take place at the beginning of the seventh year. The Sabbath-year was to bring its rest to the slave as well as to the land.

Your fathers hearkened not unto me ... —The words imply the fact already stated, that there had been a long-continued violation of the law to which the prophet refers. In Isaiah 58:6; Isaiah 61:1 (assuming the earlier date of those prophecies) we may trace a protest against that violation.
