a tale of two psalms

so psalm 105 and 106 both start similarly:

105:1 Oh give thanks to the Lord; call upon his name; make known his deeds among the peoples! 2 Sing to him, sing praises to him; tell of all his wondrous works!

106:1 Praise the Lord! Oh give thanks to the Lord, for he is good, for his steadfast love endures forever! 2 Who can utter the mighty deeds of the Lord, or declare all his praise?

but whilst ps105 spends the next three dozen verses recounting the marvelous work of God in his people, ps106 takes a different tack:

7 He is the Lord our God; his judgments are in all the earth. 8 He remembers his covenant forever, the word that he commanded, for a thousand generations, 9 the covenant that he made with Abraham, his sworn promise to Isaac, 10 which he confirmed to Jacob as a statute, to Israel as an everlasting covenant, 11 saying, “To you I will give the land of Canaan as your portion for an inheritance.”

6 Both we and our fathers have sinned; we have committed iniquity; we have done wickedness.

even the time in Egypt looks okay, until you contrast it with 106:

37 Then he brought out Israel with silver and gold, and there was none among his tribes who stumbled. 38 Egypt was glad when they departed, for dread of them had fallen upon it.

7 Our fathers, when they were in Egypt, did not consider your wondrous works; they did not remember the abundance of your steadfast love, but rebelled by the sea, at the Red Sea. 8 Yet he saved them for his name's sake, that he might make known his mighty power. 9 He rebuked the Red Sea, and it became dry, and he led them through the deep as through a desert.

they were well provided for, and thankful:

39 He spread a cloud for a covering, and fire to give light by night. 40 They asked, and he brought quail, and gave them bread from heaven in abundance. 41 He opened the rock, and water gushed out; it flowed through the desert like a river. 42 For he remembered his holy promise, and Abraham, his servant.

19 They made a calf in Horeb and worshiped a metal image. 20 They exchanged the glory of God for the image of an ox that eats grass. 21 They forgot God, their Savior, who had done great things in Egypt, 22 wondrous works in the land of Ham, and awesome deeds by the Red Sea. 23 Therefore he said he would destroy them— had not Moses, his chosen one, stood in the breach before him, to turn away his wrath from destroying them.

and were brought into the promised land:

43 So he brought his people out with joy, his chosen ones with singing. 44 And he gave them the lands of the nations, and they took possession of the fruit of the peoples' toil, 45 that they might keep his statutes and observe his laws.

34 They did not destroy the peoples, as the Lord commanded them, 35 but they mixed with the nations and learned to do as they did. 36 They served their idols, which became a snare to them. 37 They sacrificed their sons and their daughters to the demons; 38 they poured out innocent blood, the blood of their sons and daughters, whom they sacrificed to the idols of Canaan, and the land was polluted with blood. 39 Thus they became unclean by their acts, and played the whore in their deeds.

and are giving thanks to the Lord, but for different reasons:

45b Praise the Lord!

47 Save us, O Lord our God, and gather us from among the nations, that we may give thanks to your holy name and glory in your praise. 48 Blessed be the Lord, the God of Israel, from everlasting to everlasting! And let all the people say, “Amen!” Praise the Lord!

Praise the Lord indeed!
