'Possession' in the Bible

Moreover, I will bring on youThe one who takes possession,O inhabitant of Mareshah.The glory of Israel will enter Adullam.

Shepherd Your people with Your scepter,The flock of Your possessionWhich dwells by itself in the woodland,In the midst of a fruitful field.Let them feed in Bashan and GileadAs in the days of old.

Who is a God like You, who pardons iniquityAnd passes over the rebellious act of the remnant of His possession?He does not retain His anger forever,Because He delights in unchanging love.
