'Merely' in the Bible

Lamech said to his wives,“Adah and Zillah,Hear my voice;You wives of Lamech,Listen to what I say;For I have killed a man [merely] for wounding me,And a boy [only] for striking (bruising) me.

“Behold, You have made my days as [short as] hand widths,And my lifetime is as nothing in Your sight.Surely every man at his best is a mere breath [a wisp of smoke, a vapor that vanishes]! Selah.

I will run the way of Your commandments [with purpose],For You will give me a heart that is willing.

Therefore the word of the Lord to them will be [merely monotonous repetitions]:“Precept upon precept, precept upon precept,Rule upon rule, rule upon rule,Here a little, there a little.”That they may go and stumble backward, and be broken, ensnared, and taken captive.

“As often as it passes through, it will seize you;For morning after morning it will pass through, by day and by night,And it will be sheer terror to understand what it means.”

“Is a fast such as this what I have chosen, a day for a man to humble himself [with sorrow in his soul]?Is it only to bow down his head like a reedAnd to make sackcloth and ashes as a bed [pretending to have a repentant heart]?Do you call this a fast and a day pleasing to the Lord?

“Do you think that you become a king because you have much more cedar [in your palace than Solomon]?Did not your father [Josiah], as he ate and drank,Do just and righteous acts [being upright and in right standing with God]?Then all was well with him.

The [noble and] precious sons of Zion,[Once] worth their weight in fine gold,How they are regarded [merely] as earthen jars,The work of a potter’s hands!

We have given the hand [as a pledge of fidelity and submission] to Egypt and Assyria to get enough bread.
