sort and delete using Macros

[komic]

Hi,
Can some tell me how I can delete cells in different worksheets using Macros
for example
Sheet 1 Sheet2
column A Column A
1 3
2 6
3 10
4
5
6
7
9
10

I can't don't it manually because there's too much data, I need to match the column A data in Sheet2 and column A data in Sheet1 and delete the data in Sheet 1 based on the data in Sheet2

Delete based on what?
