'Modest' in the Bible

The girl was very beautiful, a virgin and unmarried; and she went down to the spring and filled her jar and came up.

Whoever exalts himself shall be humbled; and whoever humbles himself shall be raised to honor.

For everyone who exalts himself will be humbled [before others], and he who habitually humbles himself (keeps a realistic self-view) will be exalted.”

So get rid of all uncleanness and all that remains of wickedness, and with a humble spirit receive the word [of God] which is implanted [actually rooted in your heart], which is able to save your souls.

when they see your modest and respectful behavior [together with your devotion and appreciation—love your husband, encourage him, and enjoy him as a blessing from God].
