Ezekiel 30:15

Sin is Pelusium, so called from the marshes around it, on the easternmost branch of the Nile, only two-and-a-half miles from the sea. It was the frontier city, strongly fortified, and considered rightly as the key of Egypt, and hence called in the text its “strength.” It is mentioned again in Ezekiel 30:16. The expression, “distresses daily” (literally, by day), applied to Noph (Memphis), is a difficult one; it is understood by many as perpetually, but more probably means distresses in the open day. Its enemies shall make no covert attack, but come upon it boldly.
