'Resembling' in the Bible

and Zechariah, Aziel, Shemiramoth, Jehiel, Unni, Eliab, Maaseiah, and Benaiah [were to play] with harps tuned to Alamoth [that is, a high pitch];

Then I looked, and behold, in the expanse (firmament) that was over the heads of the cherubim there appeared something [glorious and brilliant] above them looking like a [huge] sapphire stone, formed to resemble a throne.
