Beeliada Probably Beeliada is a mistake for Eliada, as the LXX., Syriac, and Arabic read here.

2 Samuel 5:16 And Elishama, and Eliada, and Eliphalet.

Eliada
and Eliphalet

1 Chronicles 3:8 And Elishama, and Eliada, and Eliphelet, nine.

Eliphelet This variation merely arises from the change of a vowel. Here we have

13 persons mentioned, but only

1 Chronicles 14:11 So they came up to Baalperazim; and David smote them there. Then David said...

in Samuel; and it is probable that the duplicate Elishama and Eliphelet dying when young, were therefore omitted in the latter.
