Kyle: Maybe these links are broken in the Lexham Bible Dictionary

Beloved Amodeo and

Yes these are all broken

Actually, it is more likely that there is no link as there is no blue text. A link cannot be broken if it doesn't exist. The order in which resources were produced frequently explains missing linkage.

Yes, but oddly, this link from the same article is functional!

Archaeology

The biblical Negev is home to many archaeological sites and finds that provide insight into the written records of the ancient Near East. Yohanan Aharoni and his archaeological team are responsible for much of what is known about the remains in the Negev. Settlement in the biblical Negev began during the Chalcolithic Period (fourth millennium bc), and then declined through the Early, Middle, and Late Bronze Ages (third and second millenniums bc). Exceptions to this decline include Arad at the beginning of the Bronze Age and Tel Masos at the end. The subsequent Iron Age saw the most development in the Negev, as the kings of both the united and divided monarchies expanded south to strengthen their borders (Mazar, Archaeology, 438, 61, 95, 153, 177, 309, 370).

Eureka! Note the difference in title. It probably affected the match routine adding the link assuming they refer to the same edition of the same work.

This would be a plausible explanation for the absence of a link for the first two citations, though I'm not convinced, but the third has the same form as the active citation. Since when does an article cite two different editions within a single article?
