Jeremiah 21 and 22 are words given to Jeremiah by God to give to the kings of Judah. They are not hopeful words of consolation, rather they are words of judgment. The kings are used to hearing good words from their prophets. I am certain they did not take these words from Jeremiah well. They have not obeyed the Lord and will receive punishment for their actions. Jeremiah is given the difficult task of telling them.
Psalm 117 is only two verses long but what wonderful words of praise are contained there.
Psalm 118 is clearly a psalm meant for worship with its repeated phrases. It is a psalm telling of Gods goodness and love. This psalm is often recited on Palm Sunday. The last third of the psalm contain clear references to Jesus and more specifically his triumphal entry into Jerusalem. The words “save us” are “Hosanna” in Hebrew.
