On a natural level, "clinging" to someone clearly indicates a desire to be close to them and conjoined with them. It often has a negative connotation – it's connected with emotional neediness and a bit of paranoia – but is a good thing in proper balance in a happy marriage, with each partner putting the other ahead of friends, family and other interests. When it is used in the Bible, "clinging" generally represents mutual love. This can be in marriage, in friendships or in a general state of loving others and wishing to serve them. At the deepest level, when the idea is of "clinging to Jehovah," it represents a desire to know and follow the Lord’s commandments so that we can be ever better and loving and serving others.
