The necessity of a true king suffering unjustly

At church we just finished a sermon series on 1 Samuel. One thing I came to a new appreciation of was the significance of

• the unjust suffering of David, God's anointed king in waiting
• David's unwillingness to take the kingdom promised to him by force

[The former is described in great detail in at least 7 psalms, especially 22]

Both of these look forward to the true Davidic king (Messiah), Jesus who suffered and died unjustly but would not retaliate or take the kingdom that was his by force.

Several times Jesus explained (to uncomprehending disciples) from the Old Testament that it was necessary that he must suffer.
