isaiah 43:4 Since thou wast precious in my sight, thou hast been honourable, and I have loved thee: therefore will I give men for thee, and people for thy life. - Free Bible Online

      4. Since--All along from the beginning; for there was never a time when Israel was not Jehovah's people. The apodosis should be at, "I will give." "Since ever thou wast precious in My sight, honorable, and that I loved thee, I will give," &c. [MAURER]. GESENIUS, as English Version, takes "Since" to mean, "Inasmuch as." If the apodosis be as in English Version, "Since thou wast precious" will refer to the time when God called His people out of Egypt, manifesting then first the love which He had from everlasting towards them (Jer 31:3; Ho 11:1); "honorable" and "loved," refer to outward marks of honor and love from God.
      men . . . people--other nations for thee (so Isa 43:3).
      thy life--thy person.
