Combine multiple sheets

Hi all,

I found this vba script which is used to combine the data of multiple worksheets into one master sheet. However, I just want to copy data from row 4 downward. Please help me to achieve this. Thank you and please see below for the script :

 Sub Combine()
Dim J As Integer
On Error Resume Next
Sheets(1).Select
Worksheets.Add
Sheets(1).Name = "Combined"
Sheets(2).Activate
Range("A1").EntireRow.Select
Selection.Copy Destination:=Sheets(1).Range("A1")
For J = 2 To Sheets.Count
Sheets(J).Activate
Range("A1").Select
Selection.CurrentRegion.Select
Selection.Offset(1, 0).Resize(Selection.Rows.Count - 1).Select
Selection.Copy Destination:=Sheets(1).Range("A65536").End(xlUp)(2)
Next
End Sub
