Poole on 1 Samuel 6:13: The Ark's Joyous Return
Verse 13: And they of Beth-shemesh were reaping their wheat harvest in the valley: and they lifted up their eyes, and saw the ark, and rejoiced to see it.
[They were reaping wheat] Hebrew: the harvest of wheats (Piscator), of wheat (Junius and Tremellius). The wheat harvest followed the barley harvest by the space of one month. It was lasting to the end of May, and Pentecost was closing it (Drusius). Therefore, since the Ark was in Philistia for seven months, it was taken in the month of November (Menochius out of Sanchez).
[They saw the Ark] Which they were easily recognizing, 1. From its peculiar form. 2. Or from its covering, if it was covered, or from its splendor, if uncovered; since both within and without it was covered with golden plates (Sanchez).
[And they were glad when they had seen it (thus the Syriac, Arabic, Munster, Pagnine), לִרְאוֹת] To see (English); in seeing (Jonathan, Montanus, Piscator). Others: in inspecting it, uncovered contrary to the law, Numbers 4:5, whether it was uncovered by them, or by the Philistines (Junius). But in verse 19, mention is made of that curious inspection of the Ark, but by another expression, namely, to look in/on the Ark; that is to inspect and carefully to consider the Ark (Piscator). Because of joy, because the Ark was restored to them so suddenly, and without price, and with such a miracle (Mendoza).
