Abstract A non-local two-gluon vacuum expectation value is expanded as a power series of space-time interval x - y and possesses the translational invariance in Lorentz gauge. The coefficients of the first two terms in the power series are related to <0|B2|0> in Lorentz gauge. The value -(127MeV)2 of <0|B2|0> is estimated with the phenomenological values for the vacuum condensate <0|G2|0> and <0|ψψ|0> through the quantum chromodynamics equation of motion.
