'Soft' in the Bible

This is what the Lord has said: Further, I will take the highest top of the cedar and put it in the earth; cutting off from the highest of his young branches a soft one, I will have it planted on a high and great mountain;

And when they say to you, Why are you making sounds of grief? then say, Because of the news, for it is coming: and every heart will become soft, and all hands will be feeble, and every spirit will be burning low, and all knees will be turned to water: see, it is coming and it will be done, says the Lord.

In order that hearts may become soft, and the number of those who are falling may be increased, I have sent death by the sword against all their doors: you are made like a flame, you are polished for death.

As they put silver and brass and iron and lead and tin together inside the oven, heating up the fire on it to make it soft; so will I get you together in my wrath and in my passion, and, heating the fire with my breath, will make you soft.

Yes, I will take you, breathing on you the fire of my wrath, and you will become soft in it.

As silver becomes soft in the oven, so you will become soft in it; and you will be certain that I the Lord have let loose my passion on you.

And I will put her on the coals so that she may be heated and her brass burned, so that what is unclean in her may become soft and her waste be completely taken away.
