Usage of Verb 'Raqa'
nVerb used 11x in the Bible:
n2x to ‘stamp one’s feet’ and once to stamp something with the feet;
n4x for spreading metal, but not always in the sense of beating or hammering;
n3x for spreading out the earth, which is nowhere said to be spread by beating;
n1x for spreading the sky or the clouds.
nIt thus need not mean more than ‘spread out,’ whatever the means for accomplishing this.
