Psalms 52:8

But I am like a green olive tree in the house of God: I trust in the mercy of God for ever and ever.

But I am like a green olive tree - in contrast to the once mighty sinner. 'plucked out of his dwelling, and rooted out of the land the living' (Psalms 52:5).

In the house of God - where in spirit the righteous dwell in continual communion with Him (Psalms 15:1; Psalms 23:6; Psalms 27:4; Psalms 36:8). Contrast the temporary occupation of the temple by Antichrist (note, Psalms 52:5), and now by hypocrites and slave-like formalists (John 8:34).

Like a green olive tree. So the cedar and palm (Psalms 92:12), implying uprightness, as the green olive implies abundance of grace, peace, and prosperity. The oil-olive typifies the unction of the Holy Spirit. Compare Zechariah 4:11; Exodus 30:23.

I trust in the mercy of God for ever and ever - and therefore shall never be confounded. 'Spes confisa Deo, nunquam confusa recedit.'
