Let L be a Lie algebra over a filed F. In this paper, the author introduces the concept of
2-absorbing ideal in a Lie algebra. A proper ideal I of L is called a 2-absorbing ideal if whenever
[H, [K, J] ⊆ I for some ideals H,K and J of L, then [J,H] ⊆ I or [J,K] ⊆ I or [H,K] ⊆ I.
Some results concerning 2-absorbing ideals are given. It is shown that if P is a prime ideal, then
P is 2-absorbing ideal.
