Psalm 147

A song of praise. Interesting, it says that God gave the law and decrees to Jacob and no other nation. On one hand, it was not Jacob that received the law, but rather Moses. So, it could be using Jacob metaphorically to mean people of Jacob, I.e., Israel. Likewise, it also refers to them as a "nation", but we know there were two nations and many tribes. I don't see anything super profound but am just picking up on the various vocabulary the Bible uses. The same word "Jacob" or "nation" seems to have multiple meanings.
