The New John Gill Exposition of the Entire BibleLamentations 5:15
The joy of our heart is ceased…
ward joy was gone, as
well as the external signs of it: it "sabbatized" F25, as it may be
rendered; alluding perhaps to the cordial joy expressed formerly on
their sabbaths and other festivals, now not observed; at least, not
with that joy, inward and outward, they formerly were:
our dance is turned into mourning;
which also was used at their solemn
feasts, as well as at their common diversions, (Judges 21:21) ; but now no
more of that; but, instead of it, mourning at the calamities they were
oppressed with; and at the remembrance of mercies and privileges, civil
and religious, they were deprived of.
F25 (tbv) "sabbatizat".
