Passage
and they go both of them till their coming in to Beth-Lehem; and it cometh to pass at their coming in to Beth-Lehem, that all the city is moved at them, and they say, `Is this Naomi?'
and they go both of them till their coming in to Beth-Lehem; and it cometh to pass at their coming in to Beth-Lehem, that all the city is moved at them, and they say, `Is this Naomi?'
Ruth 1:17 Where thou diest I die, and there I am buried; thus doth Jehovah to me, and thus doth He add--for death itself doth part between me and thee.'
Ruth 1:18 And she seeth that she is strengthening herself to go with her, and she ceaseth to speak unto her;
Ruth 1:19 and they go both of them till their coming in to Beth-Lehem; and it cometh to pass at their coming in to Beth-Lehem, that all the city is moved at them, and they say, `Is this Naomi?'
Ruth 1:20 And she saith unto them, `Call me not Naomi; call me Mara, for the Almighty hath dealt very bitterly to me,
Ruth 1:21 I went out full, and empty hath Jehovah brought me back, why do ye call me Naomi, and Jehovah hath testified against me, and the Almighty hath done evil to me?'
The verse centers on "both", "till", "coming", "beth-lehem", "cometh", and "pass". It is saying that the verse draws attention to "both" and "till", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 18's "And she seeth that she is strengthening..." into verse 20's "And she saith unto them Call me...", so "both" and "till" belong inside that flow. In Ruth context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "both" and "till" with trust shaped by these words, not by a vague optimism outside the passage.
