John Trapp Complete Commentary
1 Samuel 6:13
And [they of] Bethshemesh [were] reaping their wheat harvest in the valley: and they lifted up their eyes, and saw the ark, and rejoiced to see [it].
Ver. 13. And they of Bethshemesh were reaping, &c.] And so it was in April or May that the ark was brought back, after seven months' abode among the Philistines. So that it was taken in October, or, as some will have it, in September, which was a solemn month amongst the Hebrews, and, for most part, sacred. For then, besides the new moon feast, were kept the feast of trumpets, of tabernacles, of atonement, &c., Lev 23:24-32 so that all was full of oblations and sacrifices: which because both priests and people polluted and profaned, therefore was the ark taken, and all lost that month.
Lifted up their eyes … and rejoiced to see it.] This was well done, and had they not fallen under that heavy hand of God for their later sin, they would have found in their hearts to show their joy by dedicating unto God, as those Milesians once did to Apollo, χρυσουν θερος, a harvest of gold, as the Philistines had done mice of gold.
