No weapon that is formed against thee shall prosper; and every tongue that shall rise against thee in judgment thou shalt condemn. This is the heritage of the servants of the LORD, and their righteousness is of me, saith the LORD.
Every tongue (that) shall rise against thee in judgment thou shalt condemn - image from a court of justice. Those who desire to "condemn" thee thou shalt "condemn" (Exodus 11:7; Joshua 10:21; Psalms 64:8; Romans 8:1; Romans 8:33).
Their righteousness (is) of me (Isaiah 45:24; Isaiah 46:13) - (this is) their justification from me. Their enemies would "condemn" them, but I justify and vindicate them, and so they condemn their enemies.
Remarks: Yahweh will yet take to Himself again Israel, the wife long separated from Him because of her sin. So long as she is apart from Him she hath no spiritual "children;" but when she shall be restored, a new song of joy shall be put in her mouth, because of the numberless Gentiles who shall be her spiritual progeny in the Gospel Kingdom. She shall "break forth on the right hand and on the left;" and while 'lengthening her cords' by the acquisition of new converts, she shall be careful also to 'strengthen her stakes' by grounding firmly in the faith those who are already believers. Her past 'shame and reproach' she shall 'remember no more.' For her Maker shall then manifest Himself as her 'Husband and her Redeemer.' Then first, as the result of His manifestation as "the Holy One of Israel," 'He shall be called the God of the whole earth.'
