And they respond in praising and in giving thanks to Jehovah, for good, for to the age His kindness <FI>is<Fi> over Israel, and all the people have shouted--a great shout--in giving praise to Jehovah, because the house of Jehovah hath been founded.
Ezra 3:9 And Jeshua standeth, <FI>and<Fi> his sons, and his brethren, Kadmiel and his sons, sons of Judah together, to overlook those doing the work in the house of God; the sons of Henadad, <FI>and<Fi> their sons and their brethren the Levites.
Ezra 3:10 And those building have founded the temple of Jehovah, and they appoint the priests, clothed, with trumpets, and the Levites, sons of Asaph, with cymbals, to praise Jehovah, by means of <FI>the instruments of<Fi> David king of Israel.
Ezra 3:11 And they respond in praising and in giving thanks to Jehovah, for good, for to the age His kindness <FI>is<Fi> over Israel, and all the people have shouted--a great shout--in giving praise to Jehovah, because the house of Jehovah hath been founded.
Ezra 3:12 And many of the priests, and the Levites, and the heads of the fathers, the aged men who had seen the first house--in this house being founded before their eyes--are weeping with a loud voice, and many with a shout, in joy, lifting up the voice;
Ezra 3:13 and the people are not discerning the noise of the shout of joy from the noise of the weeping of the people, for the people are shouting--a great shout--and the noise hath been heard unto a distance.
The verse centers on "for good", "respond", "praising", "giving", "thanks", "jehovah", "kindness", and "over". It is saying that the verse draws attention to "for good" and "respond", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 10's "And those building have founded the temple..." into verse 12's "And many of the priests and the...", so "for good" and "respond" belong inside that flow. In Ezra context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "for good" and "respond" with trust shaped by these words, not by a vague optimism outside the passage.
