Bulk Insert update through path value

Dear Experts,
I am using below mentioned query to update text file into database. I need to declare @path in bulk insert statement instead of hard coding. Please help.
 
Bulk Insert Emp_DB.dbo.intermediary  From '\\10.0.0.150\att\txtfile.txt' With (FieldTerminator=',', FirstRow=1, rowterminator ='\n')


Need to do like this

Declare @Path Varchar(100)
Set @Path ='\\10.0.0.150\att\txtfile.txt'


Bulk Insert Emp_DB.dbo.intermediary  From @Path  With (FieldTerminator=',', FirstRow=1, rowterminator ='\n')

Error:
Msg 102, Level 15, State 1, Procedure UpdateTxtFile, Line 14
Incorrect syntax near '@Path'.
Msg 319, Level 15, State 1, Procedure UpdateTxtFile, Line 14
Incorrect syntax near the keyword 'with'. If this statement is a common table expression or an xmlnamespaces clause, the previous statement must be terminated with a semicolon.
