'Interpret' in the Bible
You know how to interpret the appearance of the sky, yet you can't interpret the signs of the times? An evil and adulterous generation craves a sign, but no sign will be given to it except the sign of Jonah." Then he left them and went away.
You hypocrites! You know how to interpret the appearance of the earth and the sky, yet you don't know how to interpret the present time?"
Not all have the gift of healing, do they? Not all speak in foreign languages, do they? Not all interpret, do they?
Therefore, the person who speaks in a foreign language should pray for the ability to interpret it.
If anyone speaks in a foreign language, only two or three at the most should do so, one at a time, and somebody must interpret.
