ya.shar describes conduct or people judged right and wholehearted, and can describe something physically straight.

The dominant usage evaluates conduct, persons, hearts, ways, and communal instruction as right in relation to the LORD or in contrast with wickedness and crookedness. A small physical use describes the straight position of the creatures’ feet and wings.

1. Right conduct, character, and way · dominant

   The adjective marks conduct assessed as right before the LORD: in 1 Kings 15:11 the APB renders Asa as doing what was “upright in the eyes of the LORD,” while 2 Chronicles 34:2 joins this evaluation with not turning aside to the right or left. It also characterizes people and inward disposition: 2 Chronicles 29:34 describes Levites as more upright in heart for consecration, and Proverbs 11:3 says the integrity of the upright guides them.

2. Physically straight or extended · rare

   In the vision description, the feminine forms describe bodily features rather than moral conduct. In Ezekiel 1:7 the APB renders the creatures’ feet as “straight,” and in Ezekiel 1:23 it renders their wings as stretched out “straight” toward one another.

   Ezekiel 1:7Ezekiel 1:23

In the Anselm Project Bible: The APB commonly renders the evaluative use with “upright” or “right,” especially in statements about what is done in the LORD’s eyes; it renders the vision scenes with “straight.” These renderings confirm the clauses’ overall presentation rather than establish a separate English equivalent in every occurrence.
