Translation of "Fearful" in Portuguese

We told our little friends about these fearful stories

contamos aos nossos amiguinhos sobre essas histórias de medo

To make matters worse, there were signs of a fearful storm.

Para tornar as coisas piores, havia vestígios de uma tempestade terrificante.

- Who is like unto thee, O Lord, among the gods? who is like thee, glorious in holiness, fearful in praises, doing wonders?
- Who is like to thee, among the gods, O Lord? who is like to thee, glorious in holiness, terrible and praise-worthy, doing wonders?

Quem entre os deuses se assemelha a ti, Senhor? Quem é semelhante a ti, magnífico em santidade, terrível em proezas, hábil em maravilhas?
