1. They are beginning to recognise they belonged to the Lord. The word ‘purchased’ means ‘redeemed’ ‘bought’. They were the ‘sheep of His pasture.’ Exodus 15:16. There is the first breaking forth of a knowledge of the mercy of God toward them in the past. God’s people are a ‘purchased’ people. Acts 20:28; 1 Cors 6:20.
2. The phrase ‘the rod of thine inheritance’ intimate the preciousness of Israel to the Lord. The word ‘rod’ may be translated ‘staff’, something that is carried in the hand. So it is with the people of God, they are held in His hand, John 10:28-30.
3. The use of the word ‘redeemed’ is a more definite reference of Israel being the possession of the Lord. It is a word that is linked to the wonderful work of redemption. It is used in other places as a reference to Christ our ‘kinsman redeemer, Job 19:25-27, famous words indeed. The word ‘redeemer’ is the same word as ‘redeemed’ in verse 2 of our psalm.
4. Here too is a remembering of the special place Zion was to to the Lord. “This mount Zion, wherein thou hast dwelt.” Note it is past tense. At the time prophesied of here, Antichrist dominates Jerusalem and it is his ‘dwelling place’. John saw this time in his vision of future events. “But the court which is without the temple leave out, and measure it not; for it is given unto the Gentiles: and the holy city shall they tread under foot forty and two months,” Revelation 11:2.
