Find Data in one array and match the position in another array

Hello,

I have been working with a large amount of data and came across this problem. I am trying to get a formula that will find the correct data in an array and then find the data in another array for the matching position. Attached is an example.

For instance the number "8" is in position A6 in the first array and the data in the same position in the second array is "10"

I have combined and tried several different formulas, but so far nothing has done it correctly.

Thanks
