Ulangan 7:21

7:21 You must not tremble in their presence, for the Lord your God, who is present among you, is a great and awesome God.

Mazmur 24:8

24:8 Who is this majestic king? ¹ 

The Lord who is strong and mighty!

The Lord who is mighty in battle!

Yesaya 10:21

10:21 A remnant will come back, a remnant of Jacob, to the mighty God. ² 

[24:8]  ¹ sn Who is this majestic king? Perhaps the personified gates/doors ask this question, in response to the command given in v. 7.

[10:21]  ² tn The referent of אֵל גִּבּוֹר (’el gibbor, “mighty God”) is uncertain. The title appears only here and in 9:6, where it is one of the royal titles of the coming ideal Davidic king. (Similar titles appear in Deut 10:17 and Neh 9:32 [“the great, mighty, and awesome God”] and in Jer 32:18 [“the great and mighty God”]. Both titles refer to God.) Though Hos 3:5 pictures Israel someday seeking “David their king,” and provides some support for a messianic interpretation of Isa 10:21, the Davidic king is not mentioned in the immediate context of Isa 10:21 (see Isa 11, however). The preceding verse mentions Israel relying on the Lord, so it is likely that the title refers to God here.
