<p>3:7 <i>Therefore, even as the Holy Spirit said- </i>The understanding is that the words of the Old Testament are God's Spirit speaking; for this is the meaning of the Scriptures being Divinely inspired or in-spirited. The argument begun by &quot;therefore&quot; is picked up again in :12- therefore, &quot;take heed&quot;.</p><p><i>Today, if you shall hear his voice</i>- The Hebrew is an appeal: &quot;Oh that today you would hear His voice&quot;. The emphasis upon &quot;today&quot; is in the context of appealing for confidence in the certain hope of salvation (:6). We should be able to say with confidence that &quot;today&quot; if the Lord comes or if we die, we shall be saved. This is the meaning of the emphasis upon &quot;today&quot;; Peter has the same idea when writing of our rejoicing in &quot;the present truth&quot; (2 Pet. 1:12), the ultimate truth that today at this moment we shall be saved if the Lord returns or we die. In this sense &quot;now is the day of salvation&quot; (2 Cor. 6:2). At this moment we can seek and find the Lord, &quot;while He may be found&quot; (Is. 55:6). The Lord repeats the same argument by saying that &quot;If any man hear My voice... I will come in to him&quot; (Rev. 3:20). Hebrews opened with the statement that the God who spoke by the prophets has spoken to us in His Son; and it is directly from Him that we are appealed to. Hearing the Lord's voice may well allude to the Lord's statement that His sheep hear His voice; and the context of the Psalm 95 quotation is that &ldquo;He is our God, and we are the people of his pasture, and the sheep of his hand&rdquo; (Ps. 95:7 ASV). The voice of God is therefore mediated to us through the shepherd voice of the Lord Jesus.&nbsp;</p>
