We come to the end of Zechariah and find a description of God as the former shepherd who broke his own staff to represent the breaking of the covenant between him and his sheep. An interesting image because while it is the sheep who disobey, it is God who ultimately decides that the covenant must be broken forever with his people. This sets the stage for the new unconditional covenant that must come through Jesus based upon grace and providence as opposed to action and obedience.
In the Psalms we have in 84 one that is very well known and even has a contemporary song attached to it. See if you can find the verses that go with this song.
