I Agree with what you say here ---There is no contradiction between between these 2 Scriptures ----God did not disagree with Himself ------
Gal: 3:10 "All who rely on observing the law are under a curse, for it is written: 'Cursed is everyone who does not continue to do everything written in the Book of the Law'"
Psalm 119:1 Blessed are those whose ways are blameless, who walk according to the law of the LORD.
------------------------------------------------------------------------------------------------------------------------------------------
I say -----Gal:3 is in the New Testament ----where all those who have received Jesus are not under the law but under Grace and are under the Blessings ---the unbelievers are still under the curse of the law -----
Psalms 119:1 ---is in the Old testament and the law keeping is required --This verse is telling the Israelites that there is only one way to have the peace and protection of God and the Blessings of God is to Follow His laws ---otherwise the Curse awaits the disobedient ----
--We have to understand that in the Old Testament God The Father dealt directly with His faithful Servants ------and we need to understand that The Israelites wanted rules from God and said they would follow them ---so God gave them the 10 Commandments ----So the Isarelites brought in the 10 Commands themselves -----God already knew they couldn't keep them---but because of their pride the Israelits thought it would be easy to keep them -----God gave them the laws to show their sin -----the law actually brings your Sin into the Light ------
Exodus 19 NIV ----read all for yourselves to get the Context of this Scripture ----

At Mount Sinai
3 Then Moses went up to God, and the Lord called to him from the mountain and said, “This is what you are to say to the descendants of Jacob and what you are to tell the people of Israel: 4 ‘You yourselves have seen what I did to Egypt, and how I carried you on eagles’ wings and brought you to myself.
5 Now if you obey me fully and keep my covenant, then out of all nations you will be my treasured possession. Although the whole earth is mine, 6 you[a] will be for me a kingdom of priests and a holy nation.’ These are the words you are to speak to the Israelites.”
7 So Moses went back and summoned the elders of the people and set before them all the words the Lord had commanded him to speak.
8 The people all responded together, “We will do everything the Lord has said.” So Moses brought their answer back to the Lord.
I say ------so we see the people agreed to do everything God has said ------now the 10 Commandments were not the only laws God was talking about ----altogether there are 613 Laws and the Book of James says if you broke one law you broke them all -----so it was impossible for any human to keep the law and that is the same today -----and God had put the Blessings and Curses in place for not obeying Him and for Obeying Him -----So the Laws actually kept the Israelites under the Curses of disobedience because they could'n keep all the laws-----The Gentiles were not included in the laws given ---only God's Chosen nation was included ----
We have to understand that without laws there is no transgression ----you can see that with Cain who killed his brother Able ----and God said Able's Blood is crying out ----and He warns Cain that sin is crouching at his door and he must learn to master it -----Genesis 4 gives you Cain and Able -----God did Curse Cain as just punishment but He also put His mark on him for protection ------God showed His love and Mercy big time for Cain ---Cain didn't transgress any Law ---but he did disobey God with the offering he brought before him and allowed the spirit of envy and jealousy to overtake him as God liked Able's offering but not his ----
Romans 4 Niv ----see verse 15 --read the Chapter for yourselves
https://www.biblegateway.com/passage/?search=Romans 4&version=NIV
13 It was not through the law that Abraham and his offspring received the promise that he would be heir of the world, but through the righteousness that comes by faith. 14 For if those who depend on the law are heirs, faith means nothing and the promise is worthless,
15 because the law brings wrath. And where there is no law there is no transgression
i say
Jesus came to Fulfil all 613 laws and to bring the Blessing back ----under the New Covenant of Grace which is a better Covenant
The Mosaic Covenant ---the Law ---required 2 parties --we keep or not keep commands --God gives us blessings or curses ----this Covenant is worked Based
New Covenant of Grace --God is the only party ---Jesus bore all for us --all we have to do is receive by faith what God has already made available ----the Blessings are in place -----our sins are forgiven if we receive Jesus as our Lord and saviour ----which is free --we did nothing to deserve the free Graced gift of Salvation ---we didn't earn it by keep the laws ----this Covenant is Graced Based ---big difference -----
We Christians now have a mediator --Jesus ---the Son ---who goes to His Father on our behalf ---
