'Shouting' in the Bible

'And in the seventh month, in the first of the month, a holy convocation ye have, ye do no servile work; a day of shouting it is to you;

and Moses sendeth them, a thousand for a tribe, to the host, them and Phinehas son of Eleazar the priest, to the host; and the holy vessels, and the trumpets of the shouting, in his hand.
