Charles Ellicott Commentary Luke 1:36

"And behold, Elisabeth thy kinswoman, she also hath conceived a son in her old age; and this is the sixth month with her that was called barren." — Luke 1:36 (ASV)

Your cousin Elisabeth.—See Notes on Luke 1:27; Luke 1:32. Taking the word in its usual sense, it would imply that either the father or the mother of Mary had been of the house of Aaron, or that the mother of Elizabeth had been of the house of David.
