Yesaya 6:2

6:2 Seraphs ¹  stood over him; each one had six wings. With two wings they covered their faces, with two they covered their feet, ²  and they used the remaining two to fly.

Yesaya 4:6

4:6 By day it will be a shelter to provide shade from the heat,

as well as safety and protection from the heavy downpour. ³ 

[6:2]  ¹ tn Hebrew שָׂרָף (saraf, “seraph”) literally means “burning one,” perhaps suggesting that these creatures had a fiery appearance (cf. TEV, CEV “flaming creatures”; NCV “heavenly creatures of fire”). Elsewhere in the OT the word “seraph” refers to poisonous snakes (Num 21:6; Deut 8:15; Isa 14:29; 30:6). Perhaps they were called “burning ones” because of their appearance or the effect of their venomous bites, which would cause a victim to burn up with fever. It is possible that the seraphs seen by Isaiah were at least partially serpentine in appearance. Though it might seem strange for a snake-like creature to have wings, two of the texts where “seraphs” are snakes describe them as “flying” (Isa 14:29; 30:6), perhaps referring to their darting movements. See the note at 14:29.

[6:2]  ² sn Some understand “feet” here as a euphemistic reference to the genitals.

[4:6]  ³ tn Heb “a shelter it will be for shade by day from heat, and for a place of refuge and for a hiding place from cloudburst and rain.” Since both of the last nouns of this verse can mean rain, they can either refer to the rain storm and the rain as distinct items or together refer to a heavy downpour. Regardless, they do not represent unrelated phenomena.
