'Close' in the Bible

From the sacrifice of peace offerings he shall bring as an offering by fire to the Lord, its fat, the entire fat tail which he shall remove close to the backbone, and the fat that covers the entrails, and all the fat which is on the entrails,

‘No one shall approach any blood relative of his to uncover nakedness (have intimate relations). I am the Lord.

You shall not uncover the nakedness of (have intimate relations with) your mother’s sister or your father’s sister, for such a one has uncovered his blood relative; they will bear their guilt.
