Albert Barnes Commentary Acts 27:41

"But lighting upon a place where two seas met, they ran the vessel aground; and the foreship struck and remained unmoveable, but the stern began to break up by the violence [of the waves]." — Acts 27:41 (ASV)

And falling. Being carried by the wind and waves.

Into a place where two seas met. Greek: Into a place of a double sea. diyalasson. This means a place that is washed on both sides by the sea.

It properly refers to an isthmus, a tongue of land, or a sandbar, stretching out from the mainland, and washed on both sides by the waves.

Evidently, this was not truly an isthmus above the waves but was probably a long sandbank that stretched far out into the sea, which they did not perceive. In attempting to reach the harbour, they ran onto this bar or sandbank.

They ran the ship aground. Not intentionally, but in attempting to reach the harbour (Acts 27:39).

The hinder part was broken. The stern was broken or staved in. In this way, the people were supplied with boards and other pieces, on which they were safely carried to the shore (Acts 27:44).
