'Short' in the Bible

You rejoice in this, though now for a short time you have had to struggle in various trials

If you address as Father, the One who impartially judges according to each one’s work, conduct yourselves in [reverent] fear [of Him] and with profound respect for Him throughout the time of your stay on earth.

And the God of all grace, who called you to his eternal glory in Christ, [after you] have suffered for a short time, will himself restore, confirm, strengthen, [and] establish [you].

Through Silvanus, whom I regard as a faithful brother, I have written this short letter to encourage you and to testify that this is to be the true grace of God in which you are to stand firm!
