1 Chronicles 14:7  (King James Version)
And Elishama, and Beeliada, and Eliphalet.

Probably Beeliada is a mistake for Eliada, as the LXX., Syriac, and Arabic read here.
2 Samuel 5:16

and Eliphalet.

This variation merely arises from the change of a vowel. Here we have 13 persons mentioned, but only 11 in Samuel; and it is probable that the duplicate Elishama and Eliphelet dying when young, were therefore omitted in the latter.
