Yesaya 6:6

6:6 But then one of the seraphs flew toward me. In his hand was a hot coal he had taken from the altar with tongs.

Yehezkiel 1:13

1:13 In the middle ¹  of the living beings was something like ²  burning coals of fire ³  or like torches. It moved back and forth among the living beings. It was bright, and lightning was flashing out of the fire.

[1:13]  ¹ tc The MT reads “and the form of the creatures” (וּדְמוּת הַחַיּוֹת, udÿmut hakhayyot). The LXX reads “and in the midst of the creatures,” suggesting an underlying Hebrew text of וּמִתּוֹךְ הַחַיּוֹת (umittokh hakhayyot). The subsequent description of something moving among the creatures supports the LXX.

[1:13]  ² tc The MT reads “and the form of the creatures – their appearance was like burning coals of fire.” The LXX reads “in the midst of the creatures was a sight like burning coals of fire.” The MT may have adjusted “appearance” to “their appearance” to fit their reading of the beginning of the verse (see the tc note on “in the middle”). See M. Greenberg, Ezekiel (AB), 1:46.

[1:13]  ³ sn Burning coals of fire are also a part of David’s poetic description of God’s appearance (see 2 Sam 22:9, 13; Ps 18:8).
