John 1:14

And the Word became flesh, and dwelt among us (and we beheld his glory, glory as of the only begotten from the Father), full of grace and truth.

Καὶ ὁ λόγος σὰρξ ἐγένετο καὶ ἐσκήνωσεν ἐν ἡμῖν, καὶ ἐθεασάμεθα τὴν δόξαν αὐτοῦ, δόξαν ὡς μονογενοῦς παρὰ πατρός, πλήρης χάριτος καὶ ἀληθείας.

What we did

We kept the ASV's wording, in modern English.

Why

"Dwelt."
ἐσκήνωσεν means literally "pitched a tent." It is the verb of σκηνή, "tent, tabernacle," the word for the Mishkan where Yehovah's glory dwelt (Exod 40:34).
More
The same verb occurs in Revelation 7:15, 12:12, 13:6 and 21:3. "Dwelt" is accurate, so the ASV's word is kept; "tabernacled" would also be a fair rendering.
"Only begotten."
μονογενής is built on γένος, "kind," and means "unique, one of a kind." "Only begotten" is the traditional English and is kept.
"Full of grace and truth."
The pair matches the Hebrew of Exod 34:6, רַב־חֶסֶד וֶאֱמֶת, "abundant in lovingkindness and truth."
"Became."
ἐγένετο is the ordinary verb "became, came to be," rendered as the ASV has it.

Other renderings

"tabernacled among us" for ἐσκήνωσεν; "the one and only" for μονογενής.
