And the king stood by a pillar, and made a covenant before the LORD, to walk after the LORD, and to keep his commandments and his testimonies and his statutes with all their heart and all their soul, to perform the words of this covenant that were written in this book. And all the people stood to the covenant. Stood by a pillar - He stood, על העמוד al haammud, "upon the stairs or pulpit." This is what is called the brazen scaffold or pulpit which Solomon made, and on which the kings were accustomed to stand when they addressed the people. See 2 Chronicles 6:13, and the parallel places.
Made a covenant - This was expressed,
1. In general. To walk after Jehovah; to have no gods besides him.
2. To take his law for the regulation of their conduct.
3. In particular. To bend their whole heart and soul to the observance of it, so that, they might not only have religion without, but, piety within.
To this all the people stood up, thus giving their consent, and binding themselves to obedience.
