Lamentations 1:7
Jerusalem remembered in the days of her affliction and of her miseries all her pleasant things that she had in the days of old, when her people fell into the hand of the enemy, and none did help her: the adversaries saw her, and did mock at her sabbaths.
The book is Jeremiah's, the weeping prophet whose life was spent under persecution from his own people and in grief over the ruin coming upon them. The verse is part of a sad song commemorating the awful sufferings of Jerusalem's apostate people. It is Israel's funeral song, sung in a strange land after the nation's former glory had ended and never returned. In the days of her affliction and miseries after her people were taken captive, Jerusalem remembered all the pleasant good things she had enjoyed in former days.
When her people fell into the hand of the enemy and none helped her, the adversaries saw her distress and mocked her sabbaths. That mocking was over the cessation of her annual feast days and sabbaths after Jerusalem's destruction. Those annual sabbaths were appointed days within the feasts held at Jerusalem, and they could no longer be observed once the city and its assemblies were destroyed.
The words her sabbaths mean the annual sabbaths associated with Israel's feasts, distinct from the weekly Sabbath of the Lord, which is called my Sabbath. They mean the annual sabbaths associated with Israel, distinct from the Lord's weekly Sabbath, which is a memorial of creation. They are so called because they are the annual and septennial sabbaths belonging to Israel, distinct from the weekly seventh-day Sabbath, which is called the Sabbath of the Lord. The verse thus shows that the wicked mock at the Sabbath.
