The voice - i. e., the outcry and threats.

Give heed to me, O Lord,.... To his prayer, since his enemies would not give heed to his prophecies; and God does give heed to the cries and complaints of his ministers, when men will not give heed to their words and doctrines; they have a God to go to, who will hear them, when men despise them:

and hearken to the voice of them that contend with me; hear their reproaches and rantings, their blasphemies and evil speakings, their lies and falsehoods, and judge between me and them; let it appear who is in the right; vindicate my cause, and plead with them that plead against me.

Give heed to me, O LORD, and hearken to the voice of them that contend with me.

19. Give heed-contrasted with, "let us not give heed" (Jer 18:18). As they give no heed to me, do Thou, O Lord, give heed to me, and let my words at least have their weight with Thee.

18:18-23 When the prophet called to repentance, instead of obeying the call, the people devised devices against him. Thus do sinners deal with the great Intercessor, crucifying him afresh, and speaking against him on earth, while his blood is speaking for them in heaven. But the prophet had done his duty to them; and the same will be our rejoicing in a day of evil.
