θρίξ

Matthew 3:4 τριχῶν hair

John wore a garment of camel’s hair, with a leather belt around his waist. His food was locusts and wild honey.

Here: Plural, 'hairs': hair used as a fibre. The garment was cloth woven from camel hair. It was not a camel hide with the hair still on it.

Matthew 5:36 τρίχα hair

Nor should you swear by your head, for you cannot make a single hair white or black.

Here: A single hair. A byword for the smallest part of a person (compare Matthew 10:30, 'the very hairs of your head are all numbered').

Matthew 10:30 τρίχες hairs

And even the very hairs of your head are all numbered.

Here: Single hairs on the head. In Israel's scriptures they stood for the smallest, least valuable part of a person and for a number too large to count (Ps 40:12; 69:4).

Mark 1:6 τρίχας hair

John was clothed in camel’s hair, with a leather belt around his waist. His food was locusts and wild honey.

Luke 7:38 θριξὶν hairs

As she stood behind Him at His feet weeping, she began to wet His feet with her tears and wipe them with her hair. Then she kissed His feet and anointed them with the perfume.

Here: 'With the hairs': her hair is used as a towel. Like the tears, it comes before its verb for emphasis. To use it this way she had to let it down in a room full of men, and that was a striking act in her world (see setting and debates).

Luke 7:44 θριξὶν hair

And turning toward the woman, He said to Simon, “Do you see this woman? When I entered your house, you did not give Me water for My feet, but she wet My feet with her tears and wiped them with her hair.

Here: 'With her hair.' She used her own hair, which she must have let down, in place of a towel. In that culture it was a striking, very personal act.

Luke 12:7 τρίχες hairs

And even the very hairs of your head are all numbered. So do not be afraid; you are worth more than many sparrows.

Here: Individual hairs. In Israel's idiom this was a byword for something past counting and something too small to matter. Both ideas are at work here.

Luke 21:18 θρὶξ a hair

Yet not even a hair of your head will perish.

John 11:2 θριξὶν hair

(Mary, whose brother Lazarus was sick, was to anoint the Lord with perfume and wipe His feet with her hair.)

Here: Plural, 'hairs'. Her own hair served as the towel. This is the most striking and intimate detail of the remembered scene.

John 12:3 θριξὶν hair

Then Mary took about a pint of expensive perfume, made of pure nard, and she anointed Jesus’ feet and wiped them with her hair. And the house was filled with the fragrance of the perfume.

Here: 'With (her) hairs'. Her hair serves as the towel, so it must have been let down. In company that was a startling and intimate thing for a woman to do.

Acts 27:34 θρὶξ a hair

So for your own preservation, I urge you to eat something, because not a single hair of your head will be lost.”

Here: A single hair, the smallest thing a person could lose. It belongs to a proverbial Jewish saying for total safety.

1 Peter 3:3 τριχῶν of hair

Your beauty should not come from outward adornment, such as braided hair or gold jewelry or fine clothes,

Here: "Of hairs": what gets braided. The plural refers to the strands being worked into a style.

Revelation 1:14 τρίχες hairs

The hair of His head was white like wool, as white as snow, and His eyes were like a blazing fire.

Here: Plural, "hairs". This was the ordinary Greek way to speak of the hair on a head (compare Matthew 10:30, "the hairs of your head"). It points to the colour of the hair, not to any particular count or texture.

Revelation 9:8 τρίχας τρίχας hair

They had hair like that of women, and teeth like those of lions.

Here: Hair on the head, in the plural ('hairs'), the normal Greek way to speak of a head of hair. Nothing about real locusts quite matches it, which makes it one of the strangest details in the description.
