wee language question

When you use the word "entre" do you need to include the article in the words that follow?

ie, my dictionary gives the example of entre LA vie et LA mort but then further down entre ciel et terre - no article. Is the latter just an idiom?

In English we too can be between between heaven and earth but also between the devil and the deep blue sea. The articles are usually indispensible but it depends on the nouns rather than the conjunction. For example a person's name never has an article. (He stood between Fred and Peter.) I can't remember all the rules but they are not dissimilar in the two languages, neither are they identical.

I'll go and check if my grammar has anything to add.
