Hear, O my people, and I will speak; O Israel, and I will testify against thee: I am God, even thy God.
Hear, O my people, and I will speak - no longer 'keeping keeping' silence (Psalms 50:3).
O Israel, and I will testify against thee - as in Deuteronomy 31:26; Deuteronomy 31:28; Nehemiah 9:29, "Thou testifiedst against them, that thou mightest bring them again unto thy law." This shall be the object of God's final pleading with them, just before their conversion, after sore "trouble" (Psalms 50:15; Daniel 12:1). The Hebrew signifies to protest imploringly, and with the solemnity of an oath х wª'aa`iydaah (H5749) + bª-].
I am God even thy God. The preface to the Decalogue (Exodus 20:2). I, who am God of every creature, am in a pre-eminent sense THY God: a tender appeal, which prepares the way for the address which at last will touch the heart of Israel, long a wanderer from the Lord.
