Psalms 89:2

For I have said -I have deliberately come to this conclusion." Thus emphatically the poet introduces the motive for his song. He is persuaded that one stone after another will continue to be laid in the building of God's lovingkindness till it reaches to heaven itself, even though it may now seem to be a deserted ruin. Though for rhythmical reasons the verse is divided into two lines, its sense must be taken as a whole: -Lovingkindness and faithfulness shall be built up and established for ever in the heavens."

For the metaphorical use of -build" cp. Job 22:23; Jeremiah 12:16; Malachi 3:15. The choice of the word, as well as of -establish" in the next line, is suggested by their use in Psalms 89:4.

in the very heavens High as the heavens (Psalms 36:5); or in the region where it is beyond the reach of earthly vicissitudes (Psalms 119:89-90).

Many editors would read, Thou hast said … My faithfulness shall be established&c., a change partly supported by the LXX and Jer. But the structure of the Psalm is against the change, for the verses run in pairs, and Psalms 89:2 is clearly to be connected with Psalms 89:1: moreover the emphatic -I have said" is by no means superfluous.
