'Itself' in the Bible

And in the morning at sunrise, get up and rush the city; and look, when he and the troops who [are] with him come out to you, {you must act according to whatever opportunity offers itself}.

In those days there was no king in Israel. And in those days the tribe of the Danites [was] seeking territory for itself to live in, because until that day it had not been allotted territory among the tribes of Israel.
