How to select everything from two columns that have matching rows on google sheets

Question

My mobile teams rely on a spreadsheet for localization. With time I realized that each team are using their own keys rather than using the same one. I need to start from scratch and have both teams use the same key. How can I copy over all the rows that have matching keys into another sheet as depicted here?

so for example in the new sheet I would like to see something like this

identifier       | english             | arabic               | 
-----------------+---------------------+----------------------+
credit_card      |credit card          | بطاقة الائتمان        |
cash_on_delivery |cash on delivery     | الدفع نقدا عن الاستلام |
..

so notice the row where identifier iOS has cash will be ignored because the corresponding key in android label_cash doesn't match it

If your data sheet is in Sheet1 you can use the FILTER function in your other sheet.

=FILTER({Sheet1!A2:B,Sheet1!D2:D},Sheet1!A2:A=Sheet1!B2:B)

Have a look how the FILTER function works
