Hebrews 10:37

‘ For yet a very little while, He who comes will come, and will not tarry.'

For it is to that future hope that they must look. There is now not long to go (speaking from Heaven's point of view). ‘For yet a little while.' (mikron oson oson means ‘little, how much, how much', or ‘a little, a short distance'). These words are taken from Isaiah 26:20 LXX where the context is of anguish and suffering, and of final resurrection and God's judgment on His enemies. So let them take heart. His time is coming.

‘He who comes will come, and will not tarry.' Taken from Habakkuk 2:3 LXX with the article added to erchomenos to make it personal to Christ, so indicating ‘the coming one', and another slight change to the final verb. MT has, ‘because it (the time of deliverance) will surely come, it will not delay'. The writer is adapting it to the present circumstances, not quoting it as Scripture, but indicating a Scriptural theme. Not only is deliverance coming, but the Deliverer Himself.

So in a little while He Who is coming will come (Hebrews 9:28) and will delay no longer. Then all will have been worthwhile and they will receive their recompense of reward. It was only later that Peter was to remind Christians that with God a ‘little while' could be a thousand years or more (2 Peter 3:8).
