'Melt' in the Bible

And it shall be, when they say unto thee, Wherefore sighest thou? that thou shalt say, Because of the tidings, for it cometh; and every heart shall melt, and all hands shall be feeble, and every spirit shall faint, and all knees shall be weak as water: behold, it cometh, and it shall be done, saith the Lord Jehovah.

I have set the threatening sword against all their gates, that their heart may melt, and their stumblings be multiplied: ah! it is made as lightning, it is pointed for slaughter.

As they gather silver and brass and iron and lead and tin into the midst of the furnace, to blow the fire upon it, to melt it; so will I gather you in mine anger and in my wrath, and I will lay you there, and melt you.
