One shall be taken and the other left

 Matthew 24 (KJV)

⁴⁰ Then shall two be in the field; 

the one shall be taken, and the other left.

⁴¹ Two women shall be grinding at the mill; 

the one shall be taken, and the other left.

The word 'taken' means 'receive near' (Strong’s G3880)

The word 'left' means 'Sent away' (Strong’s G863)

Many use these Scriptures to support a pre-tribulation rapture theory. It would sound like they are correct, however,  we have to read the preceding verses to get the complete understanding of what is transpiring as well as look at what each word means using the Strong’s Concordance.  Scripture will also support and help interpret Scripture. 

So what does this mean "one shall be taken and the other left "?

Matthew 25 (KJV) explains....

³¹ When the Son of man shall come in his glory, and all the holy angels with him, then shall he sit upon the throne of his glory:

³² And before him shall be gathered all nations: and he shall separate them one from another, as a shepherd divideth his sheep from the goats:

³³ And he shall set the sheep on his right hand, but the goats on the left.

³⁴ Then shall the King say unto them on his right hand, Come, ye blessed of my Father, inherit the kingdom prepared for you from the foundation of the world:

⁴¹ Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels:

The sheep shall be received.  

The goats shall be sent away.
