Eighthly. This exercise is sometimes engaged in with the living voice. Whatever argument can be employed to establish the propriety of engaging vocally in any religious service is here available. The tongue is the glory of man; and with it the praise of God is proclaimed. "In his temple doth every one speak of his glory." That thought concerning God, which may not in some circumstances be expressed, may not be entertained. And if some features of his glorious character or administration are celebrated with the lips, so may all. Holy thoughts and affections unexpressed are sometimes like a fire shut up in the bones. Why should not these burst forth in the holy act of vowing and swearing to God, even as a flame, to the diffusion of a love and zeal for Him and his cause that would spread widely around? This the saints of God have felt when called to the service. In the land of Moab Israel _avouched_ the Lord to be their God; and presenting an animating example, the kingdom of Judah, with Asa their king, "sware unto the Lord with a loud voice."[167] Lastly. A Covenant with God is sometimes confirmed by subscription. Probably in imitation of the practice of the people of God, covenants among idolaters were written. "Your covenant with death shall be disannulled,"[168] (that is, _covered_ or _blotted_ out, as if it had been written.) The application of the seal was equivalent to the signature of the hand. It must have been made on occasions of federal ratification, and it might then have accompanied the subscription of the name. There is reason to believe that Nehemiah referred to an imitation of an ancient practice when he said, "And because of all this, we make a sure covenant, and write it: and our princes, Levites, and priests, seal unto it."[169] But to whatever extent the practice may have obtained in the earlier times, it possesses the highest warrant during every period that should succeed. "One shall say, I am the Lord's; and another shall call himself by the name of Jacob; and another shall _subscribe_ with his hand unto the Lord."[170] Hence, in the first place, religious Covenanting is an exercise distinct from every other. The vow cannot be mistaken for anything else; and the swearing of the oath is marked by a character of its own.
