Matthew Poole and continuators on Acts 27:40

40 And when they had taken up the anchors, they committed themselves unto the sea▪ and loosed the rudder-bands, and hoised up the main sail `to the wind, and made towards shore.

Rudders is in the Plural Number put for the Singular: Or rather, in those times they having Two Rudders (as by several passages amongst the Ancients do appear), they were both loosed, that now they might use them to direct the ship to the best advantage in making the shore, they having been tied whilst they were a-drift, or at Anchor.

Which they had let down, or struck, ver. 17. and now that they might make some use of the winds, to get nigher to the shore, they hoised up. As God doth instruct the Plowman, Isa. 28 26. so he teacheth the Mariner, and every one in their Calling.

Marginal references: Or, cut the anchors, they left them in the Sea, &c.
