When the ark was brought to Jerusalem and placed in the tent David had pitched for it (1 Chronicles 16:1), he wrote this song of thanksgiving that comprises the central part of 1 Chronicles 16 (verses 8-36).
8 Give thanks unto the LORD, call upon his name, make known his deeds among the people.
9 Sing unto him, sing psalms unto him, talk ye of all his wondrous works.
10 Glory ye in his holy name: let the heart of them rejoice that seek the LORD.
11 Seek the LORD and his strength, seek his face continually.
12 Remember his marvellous works that he hath done, his wonders, and the judgments of his mouth;
13 O ye seed of Israel his servant, ye children of Jacob, his chosen ones.
14 He is the LORD our God; his judgments are in all the earth.
15 Be ye mindful always of his covenant; the word which he commanded to a thousand generations;
16 Even of the covenant which he made with Abraham, and of his oath unto Isaac;
17 And hath confirmed the same to Jacob for a law, and to Israel for an everlasting covenant,
18 Saying, Unto thee will I give the land of Canaan, the lot of your inheritance;
19 When ye were but few, even a few, and strangers in it.
20 And when they went from nation to nation, and from one kingdom to another people;
21 He suffered no man to do them wrong: yea, he reproved kings for their sakes,
22 Saying, Touch not mine anointed, and do my prophets no harm.
23 Sing unto the LORD, all the earth; shew forth from day to day his salvation.
24 Declare his glory among the heathen; his marvellous works among all nations.
25 For great is the LORD, and greatly to be praised: he also is to be feared above all gods.
26 For all the gods of the people are idols: but the LORD made the heavens.
27 Glory and honour are in his presence; strength and gladness are in his place.
28 Give unto the LORD, ye kindreds of the people, give unto the LORD glory and strength.
29 Give unto the LORD the glory due unto his name: bring an offering, and come before him: worship the LORD in the beauty of holiness.
30 Fear before him, all the earth: the world also shall be stable, that it be not moved.
31 Let the heavens be glad, and let the earth rejoice: and let men say among the nations, The LORD reigneth.
32 Let the sea roar, and the fulness thereof: let the fields rejoice, and all that is therein.
33 Then shall the trees of the wood sing out at the presence of the LORD, because he cometh to judge the earth.
34 O give thanks unto the LORD; for he is good; for his mercy endureth for ever.
35 And say ye, Save us, O God of our salvation, and gather us together, and deliver us from the heathen, that we may give thanks to thy holy name, and glory in thy praise.
36 Blessed be the LORD God of Israel for ever and ever. And all the people said, Amen, and praised the LORD.
Many of the verses in this song of thanksgiving are echoed in various Psalms, showing the importance of giving glory and thanks to the LORD, worshipping and praising Him, and fearing Him because He created the heavens and will return to judge the earth.
Sing unto the LORD, all the earth; shew forth from day to day his salvation. (1 Chronicles 16:23)
Verse 23 of 1 Chronicles 16 is beautifully expanded upon in Psalm 96, which emphasizes that all of creation not only knows the LORD but also praises Him with gladness and joy.
1 O sing unto the LORD a new song: sing unto the LORD, all the earth.
2 Sing unto the LORD, bless his name; shew forth his salvation from day to day.
3 Declare his glory among the heathen, his wonders among all people.
4 For the LORD is great, and greatly to be praised: he is to be feared above all gods.
5 For all the gods of the nations are idols: but the LORD made the heavens.
6 Honour and majesty are before him: strength and beauty are in his sanctuary.
7 Give unto the LORD, O ye kindreds of the people, give unto the LORD glory and strength.
8 Give unto the LORD the glory due unto his name: bring an offering, and come into his courts.
9 O worship the LORD in the beauty of holiness: fear before him, all the earth.
10 Say among the heathen that the LORD reigneth: the world also shall be established that it shall not be moved: he shall judge the people righteously.
11 Let the heavens rejoice, and let the earth be glad; let the sea roar, and the fulness thereof.
12 Let the field be joyful, and all that is therein: then shall all the trees of the wood rejoice
13 Before the LORD: for he cometh, for he cometh to judge the earth: he shall judge the world with righteousness, and the people with his truth.
Let us all, always, praise the LORD, for “his mercy endureth for ever” (this phrase is repeated 41 times in the Old Testament: 1 Chronicles — 2 verses; 2 Chronicles — 4 verses; Ezra — 1 verse; Psalms — 33 verses; Jeremiah — 1 verse). And let us love the LORD with all of our heart, soul, mind, strength (Mark 12:20) for He first loved us (1 John 4:19). Amen.
