Ezekiel 16:60 - Ellicott's Commentary On The Whole Bible

I will remember my covenant. — The remembrance of God’s covenant is made the basis of His mercy to His penitent people (Leviticus 26:42-45) from the beginning, and it is often spoken of as an everlasting covenant. In the New Testament (Luke 1:54-55; Luke 1:72-73, &c.) this covenant is regarded as fulfilled in the Christian dispensation. At the same time, the Christian covenant is described as new in Jeremiah 31:31-34; it was both the continuation and designed fulfilment of the old, and in its superiority and plainer revelation of the Divine will was new. Hence the contrast between My covenant here and Thy covenant in the following verse. The covenant to be afterwards established shall be “an everlasting covenant.”
