'Assemble' in the Bible

Declare in Judah, and publish in Jerusalem; and say, 'Blow the trumpet in the land!' Cry aloud and say, 'Assemble yourselves! Let us go into the fortified cities!'

Why do we sit still? Assemble yourselves, and let us enter into the fortified cities, and let us be silent there; for Yahweh our God has put us to silence, and given us water of gall to drink, because we have sinned against Yahweh.

Is my heritage to me as a speckled bird of prey? are the birds of prey against her all around? Go, assemble all the animals of the field, bring them to devour.
