JMNT(i)
10 Now if Timothy can (or: may; should) come, be constantly seeing [to it] that he should come to be fearless toward you folks, for he continues actively working (or: performing as a worker on/in) the Lord's [= Christ's or Yahweh's] work (deed; action), as I also [do].
11 No one, then, should make nothing of him (scorn, despise or treat him with contempt; slight him), but should send him forward in peace (= with shalom) with funds and supplies, so that he can (may; should) come toward me, for I continue receiving [benefit] from out of him, together with the brothers (= fellow believers).
12 Now concerning Apollos, the brother, I called him to my side many [times] to give aid, comfort and encouragement (or: = I strongly urged him), to the end that he should go to you folks with the brothers, and yet there was not altogether a purpose so that he should go now (or: but it was not wholly [his] will {or: it was undoubtedly not [His] intent} that he should go at the present time), yet he will proceed in going (or: coming) whenever there may be a good situation (or: he may have an opportunity).
