SEV Biblia, Chapter 30:21
¶ Así hicieron los hijos de Israel, que fueron presentes en Jerusalén, la solemnidad de los panes sin levadura por siete días con grande gozo; y alababan al SEÑOR todos los días los levitas y los sacerdotes, con instrumentos de fortaleza al SEÑOR.
John Gill's Bible Commentary
Ver. 21. And the children of Israel that were present at Jerusalem kept the feast of unleavened bread seven days with great gladness , etc.] Which, according to the law of Moses, were always to follow the passover, ( Exodus 12:18,19) and the Levites and the priests praised the Lord day by day, singing with loud instruments unto the Lord ; or instruments of strength f130 ; so called not from the matter of them, or manner in which they were made, but either from the sound of them, as our version, or from the strength and power of God, which they set forth in praise; the Targum is, “with instruments of praise,” and so the word is sometimes used, (see Psalm 8:2) compared with ( Matthew 21:16), the priests blew with trumpets, and the Levites played on harps, psalteries, etc. and this they did every day when the sacrifices were offered, during the seven days of unleavened bread.
Matthew Henry Commentary
Verses 21-27 - Many prayers were put up to God with the peace-offerings. In thes Israel looked to God as the God of their fathers, a God in covenan with them. There was also abundance of good preaching. The Levites rea and explained the Scriptures. Faith cometh by hearing, and tru religion preaching has abounded. They sang psalms every day: praisin God should be much of our work in religious assemblies. Having kept the seven days of the feast in this religious manner, they had so muc comfort in it, that they kept other seven days also. This they did with gladness. Holy duties should be done with holy gladness. And when sinners humble themselves before the Lord, they may expect gladness in his ordinances. Those who taste this happiness will not soon grow wear of it, but will be glad to prolong their enjoyment __________________________________________________________________
