SEV Biblia, Chapter 31:17 y a los que eran contados entre los sacerdotes por las familias de sus padres, y a los levitas de edad de veinte años arriba, por sus estancias y órdenes;
Clarke's Bible Commentary - 2 Chronicles 31:17 Verse 17. From twenty years old] Moses had ordered that the Levites should not begin their labour till they were thirty years of age; but David changed this order, and obliged them to begin at twenty.

Both to the genealogy of the priests by the house of their fathers , etc.] As to the priests registered according to their families from the age before observed, a portion was given: so to the Levites, from twenty years old and upward, in their charges, by their courses ; for though originally they were not admitted into the tabernacle till twenty five years of age, nor to officiate till thirty, but in David’s time they were allowed at twenty years of age and upwards, ( 1 Chronicles 23:24).
Matthew Henry Commentary Hezekiah destroys idolatry.
--After the passover, the people of Israel applied with vigour to destroy the monuments of idolatry. Public ordinances should stir us u to cleanse our hearts, our houses, and shops, from the filth of sin and the idolatry of covetousness, and to excite others to do the same The after-improvement of solemn ordinances, is of the greates importance to personal, family, and public religion. When they ha tasted the sweetness of God's ordinance in the late passover, they wer free in maintaining the temple service. Those who enjoy the benefit of a settled ministry, will not grudge the expense of it. In all tha Hezekiah attempted in God's service, he was earnest and single in his aim and dependence, and was prospered accordingly. Whether we have fe or many talents intrusted to us, may we thus seek to improve them, an encourage others to do the same. What is undertaken with a sincer regard to the glory of God, will succeed to our own honour and comfor at last __________________________________________________________________
