During the next decade the people once more enjoyed the comforts of peace, and Samuel took measures that prosperity should not efface the good results of previous misfortunes. It was his earnest endeavour to consolidate the union between the tribes, which was the true foundation of their strength. Year after year he called together the elders of the people, explained to them their duties, and reminded them of the evil days which had befallen the Israelites through their godlessness, their intermarriage with strange nations, and their idolatrous excesses; he also warned them against a return to these errors. Such assemblies Samuel held by turns in the three towns which came into notice after the destruction of Shiloh--namely, in Bethel, in Gilgal, and in Mizpah where prayers for victory over the Philistines had been offered up in the former campaign. At Ramah, the place of his residence, frequent meetings of the various tribes took place; and here the elders sought his advice in all important matters. At divine services Samuel not only caused sacrifices to be offered up, but with the aid of the Levites he introduced the use of stringed instruments in order to arouse the devout feelings of the people. Through him a new element was introduced into the divine service of the Israelites--viz., songs of praise. Samuel, the ancestor of the celebrated psalmists, the sons of Korah, was the first who composed songs of praise for divine service. His grandson, Heman, was considered the chief psalmist and musician, and he ranked in fame with Asaph and Jeduthun, who flourished in the subsequent generation. The charms of poetry and music were by Samuel brought to bear upon the religious service, and they left a lasting and ennobling impression on the minds of the people. The employment of choirs of Levites and singers rendered the sacrificial rite of minor importance. The priests, the sons of Aaron, took up a less respected position, and were, to a certain extent, neglected by Samuel. Achitub, a grandson of Eli, had saved himself after the destruction of Shiloh by taking refuge in the small town of Nob, near Jerusalem. He had carried away with him the high priest's garments; and various members of the house of Aaron having assembled there, Nob became a sacerdotal town. Here, it seems, Achitub had erected an altar, and also a tabernacle on the model of the one which had been destroyed in Shiloh. He even appears to have made an Ark of the Covenant in Nob, instead of the one carried off by the Philistines. The Israelites apparently disregarded the fact that the new ark was wanting in the essential contents,--the stone tablets of the Covenant.
