Why was no one there when I came?
When I called,
why was there no one to answer?
Is my hand shortened at all, that it cannot redeem?
Or have I no power to deliver?
Behold, at my rebuke I dry up the sea,
I make the rivers a wilderness;
their fish stink because there is no water,
and they die of thirst.

“Why was no one there when I came?” God is making the point that He had come to Israel and called to Israel to bring them back to Himself, but Israel would not repent and return to Him.
